Hailey and Justin Bieber to Kristen Bell and Dax Shepard: 10 celebrity couples who didn't sign a prenup.

Celebrity prenups certainly aren't rare. 

And considering how many celebs decided to split in 2020 alone, that's probably a good thing. 

These days, many Hollywood A-listers decide to sign on the dotted line and get a prenup to protect their assets in the chance of a divorce. And when those 'assets' are million dollar mansions, who can blame them?

But there's also a bunch of celebs that choose to skip the process altogether.

For some of these couples not getting a prenup is an act of good faith, but for others it's a decision that ends up costing them hundreds of millions of dollars years later (we're looking at you Mel Gibson).

From Hailey and Justin Bieber to Kristen Bell and Dax Shepard, here are 10 celebrity couples who decided to skip the paperwork and not get a prenup.

Seth Rogen ignored everyone's advice when he decided not to sign a prenup with his wife Lauren Miller. 

The Bad Neighbours actor was asked about the decision back in 2011 while on The Howard Stern Show. 

"I’m not [getting one]," said Rogen, before adding, "My business manager told me to get one too".

"Marriage can be expensive and if I lose millions then it’ll be the best millions I’ve spent."

The couple will celebrate their 10-year wedding anniversary this year.

Hailey Bieber was only 21 when she tried the knot to 24-year-old Justin in a secret courthouse wedding in September 2018. 

The couple later had a second wedding in front of family and friends during a lavish ceremony the following year. 

According to TMZ, both Hailey and Justin reached out to their lawyers for a prenup on the day of their first wedding. However, there was no time to get a prenup drafted and signed that quickly so they had to go without. 

It looks like everything worked out though as the couple are still going strong.

Jessica Simpson regrets not signing a prenup when she married Nick Lachey in 2002. 

Speaking about their four-year marriage on Dr. Oz, the singer said, "I wish I would have signed a prenup".

"The funny thing is that Nick wanted me to sign a prenup, but I was, like, so offended."

Simpson went on to say that she didn't think a prenup was necessary because she thought the pair would never split. 

"I was like, ‘We're going to be together for the rest of our lives. We're saying our vows to God and in front of all of our family and friends. Like, this never gonna end.' And, we didn't sign a prenup."

Dax Shepard wanted to get a prenup "really bad" when he married Kristen Bell eight years ago. 

"When we first started dating, I had more money than her, and I owned the house that I lived in," Shepard told Conan O'Brien in 2018. 

"And she said to me at one point, 'Would you like a prenup?' I said, 'No, I don't want a prenup.' But I really wanted a prenup." 

In the end the pair decided to skip one. 

"Something good came over me for once, and I made the right decision," he explained. 

"But the joke is now on her because she's become much more successful than me, and has much more money than me."

But the comedian decided to walk away without a cent. 

"Russell and Katy did NOT have a prenup. As a result, everything they earned during their 14-month marriage is community property — which means they’re each entitled to 50 per cent of the pot," a source told TMZ at the time. 

"This divorce is as amicable as it gets, and Russell was a mensch [Yiddish for a good person]".

"We've grown together as a couple, and we really consider each other and put our relationship first. By doing that, you become a lot more solid. I can't imagine spending time with anyone but her," de Rossi told People earlier this year.  

"We think the same things, say the same things at the same time, finish each other's sandwiches – no, sentences. We're in a rhythm that's easy," added DeGeneres.
