It's been a hot minute since Rachel Bilson was on the O.C. and we were all obsessed with following her every move.
She never had much of scandalous dating history, choosing a long term, serious relationships over dating around, or constant breakups.
Now, she has recently made her red carpet debut with new boyfriend Bill Hader, confirming the pair are dating. Both have recently been divorced and have children, meaning they're most likely on the same page about where things will go between them.
Rachel Previously Dated Her 'O.C.' Co-Star Adam Brody
In 2003, Rachel started dating her O.C. co -star Adam Brody, and fans everywhere rejoiced. They played the cutest couple on the show, Seth and Summer, with fiction becoming real when sparks flew on set.
Unfortunately, all that hope came to nothing when they broke up in 2006, and our hearts were torn to shreds.
Despite their breakup, the pair clearly remained friends, even bumping into each other at the airport last summer. Rachel posted an Instagram photo of the two larking around, with the caption, "Ran into my ol buddy from jfk to lax #californiaherewecome."
Who doesn't love a reunion of characters from our favorite nostalgic shows?
She Was Engaged To Hayden Christensen
In 2007, Rachel met Hayden Christensen when they starred alongside each other in the movie Jumper, as per usual when it comes to Hollywood relationships.
However, after a decade together the two split up in 2017, with distance being blamed as one of the factors.
A source told Us Weekly at the time, "She’s full-time back in L.A. He’s in Toronto. They’ve been on the outs for a couple of months." They split once in 2010 after getting engaged two years earlier, but got back together not long after. In 2014, the couple welcomed a daughter together.
Rachel Spoke About Life As A Single Mom
Last summer, Rachel appeared on an episode of Nick Viall's podcast, The Viall Files, and spoke about raising her daughter as a single mother while trying to date at the same time.
She claimed the reaction to her daughter could raise red flags, saying, "I was talking to these guys a few months back, anytime I would bring my daughter up, they 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."
She concluded, "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."
She Debuted Her Relationship With Bill Hader At 'The Golden Globes'
Rachel was rumored to be dating actor Bill Hader for months, after they were spotted grabbing coffee in his hometown of Tulsa, Oklahoma.
Hader recently divorced his wife Maggie Carey who directed The To Do List, a movie that both Rachel and Bill starred in together in 2013 (interesting!)
They recently made their official debut as a couple at the recent Golden Globe Awards confirming months of rumors.
With both having kids and recently divorced, it appears they can relate on many levels. Despite the couple coming as quite a surprise, perhaps things will last long term for them.
