The end of a relationship is never easy to navigate, and that’s especially the case in Hollywood. However, there is no denying that some celebrity divorces go more smoothly than others.

Over the years, there have been A-list lovers who have decided to consciously uncouple after years of marriage. They navigate splits with ease and go on with their lives relatively unscathed.

Other divorces come with a bit more drama. Some are plagued with rumors of infidelity that generate endless headlines. There can be legal battles that play out for years over spousal support, custody issues and so much more.

While drama can play out in court, sometimes it comes in other forms such as songs and memoirs, which unearth old memories.

We rounded up 20 of the most contentious celebrity divorces and recapped what made them so tense.

Jesse James and Alexis DeJoria are calling it quits.

The reality star and mechanic – who hosts Monster Garage – announced he is parting ways with the professional drag racer on Instagram on Tuesday (March 17).

“I know a lot of you have been asking if I will be attending the NHRA races this year to work on Alexis’ funny car,” Jesse wrote. “Its with an incredible amount of sadness to let you know Alexis and I have decided to end our marriage.”

“We spent close to seven amazing years together,” he continued. “Working on her race car for five of those years was one of the highlights of my life. Also a highlight was trying my best to be a good dad to her daughter. Something that will leave a huge hole in my heart forever.”

“Unfortunately at the end of the day our lives were just headed in different directions,” he added. “Creating a distance that was insurmountable. I wish her the absolute best in her racing and life. I hope you can respect our privacy in this tough time. Thank you.”

Alexis DeJoria is Jesse James’ fourth wife. He was previously married to Karla James, Janine Lindemulder, and Sandra Bullock (hear what he had to say about his split with Sandra).

Sandra Bullock is happier than ever with her boyfriend Bryan Randall!

The 52-year-old Ocean’s Eight actress has been dating the photographer for almost two years now, and they’re definitely in a good spot, according to E! News.

“Life after Jesse [James] was really tough,” a source reported, referring to Sandra‘s ex-husband. “She was embarrassed by what he did and in ways blamed herself at the time (she knows now it wasn’t her at all). She did consider Jesse a father to [her seven-year-old son] Louis, so that was one of the hardest parts of breaking up. Jesse was there for her through the whole adoption process. She now knows she is much better off and everything happens for a reason.”

“She is an independent mom and also found a great man that loves her and her kids unconditionally,” the insider went on. “Her children are her life and always have been her top priority. She lived just for her child Louis for a while and stayed away from dating to focus on herself and Louis. It took Sandy some time to actually open up to a man, trust and love again.”

The source added that Sandra is currently at the “top of her game at work” and “more in love now” than she has ever been.

“Her life is more private as well,” the insider dished. “She has let go of what happened in the past and has moved on to the future. [Sandra and Bryan] are perfect. They have been both working so it was hard for them to see each other as often as they normally do, but while Sandra works Bryan helps out with the kids. He is like the kids’ dad. He is a great guy and makes Sandra really happy.”

Jesse James is opening up about his split from ex-wife Sandra Bullock and how losing his adopted son Louis was the hardest part of it all.

The couple broke up in early 2010 after five years of marriage when it was revealed that Jesse had been having an affair.

“The relationship part I was able to put [aside],” Jesse said in an interview for In Depth with Graham Bensinger. “I had to stand up in front of the media and take full account for what I did. And I took it all. I took 100 percent of it right on the chin. Nobody does that. Everybody denies it… I’m the guy that ruined my marriage because I banged some stripper. There’s got to be some flaw in my personality that made me think that was okay.”

“The painful part was about Louis, who we adopted,” he added about the son that they adopted in January 2010. “As bad as stuff was between us, we adopted a kid and things got kind of good for a little while and we had that kid to focus on, and, boom, it was over in 24 hours – gone, done.”

“I got divorced and lost a kid I adopted because of it,” Jesse continued while discussing Louis. “Whether that’s fair, whether I should have lost a kid due to infidelity, which I don’t think anybody ever does. But I think with ‘Hollywood Law’ that’s totally fair.”

Sandra Bullock carries her son Louis while heading to a Thanksgiving party with her father John on Wednesday (November 21) in Beverly Hills, Calif.

The 48-year-old actress’ ex-husband Jesse James is reportedly engaged to be married for the fourth time to drag racer and Paul Mitchell heiress Alexis DeJoria. The pair have only been dating for a few months, according to the Huffington Post.

Jesse‘s previous relationships with Sandra and later with Kat Von D both ended in cheating scandals.

It’s over for Kat Von D and Jesse James – yet again.

“I am not in a relationship. (And I apologize for all the “back and forth” if it’s caused any confusion),” the 29-year-old tattoo artist wrote on her Facebook page.

A source also confirmed the split to People.

Kat and Jesse, 42, got re-engaged in August after splitting earlier in the summer.

Kat also set the record straight about moving to Texas, where Jesse lives.

“I am not opening up another tattoo shop. And I am not leaving my shop here in Los Angeles, High Voltage Tattoo,” she shared.

Kat Von D and Jesse James‘ engagement is back on!

“Sometimes you are only given one chance in life,” Jesse, 42, told People. “It was up to me to open my eyes and see it. That girl is my chance. I will never stop fighting and striving to hold on to her. Showing her how special she is, and how much I love her.”

The on-again couple, who initially split in late July, also each posted pics of them together on their Twitter accounts.

Jesse wrote “para siempre” – Spanish for “forever” – with a photo of him kissing Kat, 29.

The engagement news comes on the same day that TLC announced it was ending Kat‘s show LA Ink.

Kat responded, telling People, “In an effort to capitalize on my recent breakup, the network has decided to focus their energy on re-editing events that didn’t happen while filming. I have no regrets and am very proud of the original footage. In my opinion, any attempt to compromise the honesty of that would be an insult to my fans and viewers.”

Jesse James and Kat Von D have ended their engagement and relationship.

“I am no longer w Jesse, and out of respect for him, his family and myself, thats all the info I’d like to share. Thanks for respecting that,” Kat, 29, tweeted.

Jesse, 42, told People, “I’m so sad because I really love her. The distance between us was just too much.”

The two got engaged in January and were planning to tie the the knot this summer.

Jesse was previously married to Sandra Bullock, who turns 47 today. Their divorce was finalized in June 2010.

An amazing woman who stood behind me when the world turned their backs,” Jesse told People. “I have never met anyone so kind and loving and committed to making the world a better place every day. My love for her is beyond description. So honored that she said ‘yes.’ Growing old with her is going to be a f—-n’ blast!”

Jesse James has shared his thoughts on his split from Sandra Bullock.

Here’s what Jesse told People:

“My whole life has been full of hard decisions.

“The decision to let my wife end our marriage, and continue the adoption of Louis on her own, has been the hardest. The love I have for Louis cannot be put to words. Not having him around to love and to hold has left a huge hole in my heart.

“Sandy is the love of my life, but considering the pain and devastation I have caused her, it would be selfish to not let her go. Right now it is time for me to beat this addiction that has taken two of the things I love the most in life.

“I have always taken great pride in proving people wrong. That time has come once again to show that I am not what everyone says I am. I know in my heart that I can be the best father possible to my four children, and the mate Sandy deserves, and realize that this is an incredible mountain to climb. But I believe that the steps I have taken in the last 30 days are the foundation for making this happen. The lifelong commitment I am making is what being a real husband and father is all about.

“I ask that you please do not judge Sandy for the things I have done. She has done no wrong. She played no part in any of this. She has been an amazing wife, mother, and best friend, for the over 6 years we have been together.”

Sandra Bullock has spoken out about internet reports alleging a sex tape with her and hubby Jesse James.

“There is no sex tape,” Sandra said in a statement (via People). “There never has been one and there never will be one.”

Internet reports surfacing over the weekend alleged that Jesse and Sandra took part in explicit sexual acts and taped the events.

Until today, Sandra, 45, had not broken her silence on any reports about Jesse‘s infidelity or their marital crisis.

Jesse James has checked himself into a treatment facility to deal with his personal issues.

The 40-year-old West Coast Choppers head “realized that this time was crucial to help himself, help his family and help save his marriage,” his rep told People.

Before checking in, Jesse went about his normal routine, taking his little ones to school and going to work in Huntington Beach, Calif.

Sandra Bullock, Jesse‘s wife, moved out of the family home in mid-March after rumors of Jesse‘s infidelity broke.

If Sandra Bullock and Jesse James wind up getting a divorce, don’t worry, the couple entered into a prenuptuial agreement prior to their 2005 marriage!

“They keep everything separate,” an insider tells E!. “She has her money and he has his. They both wanted it that way.”

But Sandra‘s reps have already denied reports that she is looking into divorce as an option: “Neither she nor her representatives have contacted or shopped around for divorce lawyers.”

Jesse‘s reps have echoed the same sentiment.
