'Isn't that crazy?' Rachel Bilson said she had never had an orgasm from sex until she was 38.

Rachel Bilson recently opened up about what she misses the most about her ex-boyfriend, comedian Bill Hader.

When asked on her podcast Broad Ideas what she missed about the relationship, the actor replied, "His big d*ck," before bursting into laughter. 

"We can keep that... and cut, let's move on," she added.

And this week, Bilson opened up more about all things intimacy, sharing that she had never experienced an orgasm from sex until after the age of 38. 

"Now that I'm not on birth control, my sex drive ... by the way, I'm going to say this, wild thing. I have not had an orgasm from sex until I went off birth control. Never had it in my life until I turned 40... But I could do it with my hands. It didn't happen for me until I was about 38. Isn't that crazy?" she said on her podcast.

"The things that my friends and I talk about shouldn't be taboo, you know?" she said last year to Yahoo. "It should feel like a safe space to be open, because so many people go through similar things. And what's better than to have a support system, or feel like you're being heard and having a space to do so?"

Bilson and Hader split in July 2020 after making their first public appearance at the Golden Globes in January that same year.

Speaking about their split on a previous episode of her podcast, the 41-year-old admitted that their mid-pandemic break-up "hurt like a motherf**ker".

"I had nothing else to do but sit in it, deal with it, and feel it," Bilson shared.

"It was probably the hardest thing I've ever done. Harder than childbirth. If you actually face it, you can come out of it and be like, 'Okay, I did that, and I’m ready for the next thing.'"

Here's what we know about Rachel Bilson's relationships over the years.

Rachel Bilson and Adam Brody.

Rachel Bilson and Adam Brody were an insanely popular couple after their on-screen love translated into real life.

Bilson and Brody played Orange County teenagers Summer Roberts and Seth Cohen on the hit teen drama The O.C., which ran from 2003 to 2007.

The young couple started dating after meeting on set, but they kept their relationship fairly private. All we really know about them is they shared a Pitbull named Penny. That's it.

Then, it happened. In 2006, Bilson and Brody broke up in real life.  

"It was a typical romance, and they just grew apart," a source told People at the time.

Rachel Bilson and Hayden Christensen.

Rachel Bilson and Star Wars actor Hayden Christensen were together for nearly a decade. But despite being engaged at one point and sharing a child, they never actually got married.

Like most celebrity couples, they met on a film set. To be specific, the year was 2007, and the movie was a sci-fi action flop called Jumper.

Bilson and Christensen quickly got engaged the following year, only to call off said engagement in 2010. They got back together just a few months later.

As far as celebrity relationships go, Bilson and Christensen kept theirs relatively private. Aside from attending events together and the occasional social media post, they were definitely not your average high-profile couple. 

In October 2014, Bilson gave birth to their daughter, Briar Rose.

The couple then split for the last time in September 2017, citing their cross-continental work commitments.

"She's full-time back in L.A. He’s in Toronto. They’ve been on the outs for a couple of months. They are completely, officially done," a source told Us Weekly at the time.

The quiet, off-market sale of their US$3.8 million ranch in San Fernando Valley, Los Angeles, suggests they'd been separated for a few months prior.

Speaking to People in 2018, Bilson said she and Christensen are navigating co-parenting their now eight-year-old daughter.

"We're still kind of trying to figure it out, it’s a tricky one. And I don’t know that there is any right way, necessarily. We say Mummy has a house and Daddy has a house," she said.

"Most important for me is that Briar is okay and secure and stable. No matter what I'm dealing with or how much it hurts or how much anger there is, it's just about her. Briar needs to feel loved from the people she loves the most. She has that love that is unconditional, so I think we’re doing okay."

Bill Hader and Rachel Bilson confirmed their relationship by appearing at the Golden Globes together in January 2020.

Rumours that Hader, best known for his performances on SNL and in the TV dark comedy Barry, and Bilson started when they were seen grabbing coffee in Hader's hometown of Tulsa, Oklahoma, in December 2019.

Hader and Bilson likely first met when they filmed a very awkward sex scene with each other in the 2013 rom-com The To Do List. Interestingly, the film was directed by Hader's then-wife Maggie Carey. (They separated in 2017 after 11 years together. They also have three daughters, Hannah, Harper and Hayley.)

Rachel Bilson on dating as a single mum.

In July 2019, before she began dating Hader, Bilson spoke candidly about the realities of dating as a single mum.

Speaking on The Viall Files podcast, she said she hadn't introduced her daughter Briar to any of the people she'd dated since splitting with Christensen. (It's unclear whether Bilson and Hader ever met each other's children.)

Bilson also said she wouldn't date anyone who wasn't okay with her being a mum.

"I always put it out there. [Briar] is my world and I talk about her all the time... how f***ed up would it be if I hid that? If you’re going to pursue something with someone, they have to be interested in the kid or be willing to be around the kid or babysit the kid," she said.

"I was talking to this guy a few months back and anytime I would bring my daughter up, [he] would never pursue the question or ask more about her. It was a red flag because anyone that you’re going to get involved with, if you have a kid, they have to be all about the kid."
