Rachel Bilson is sharing secrets about dating in the public eye. "[Adam Brody and I] were a couple on the show and a couple in real life, [fans are] like, 'Oh, it's Seth and Summer' and they really relate it to that," Bilson, 44, recalled on the Tuesday, January 20, episode of the "Let's Be Honest" podcast. "They think that's what you are [and] who you are." Bilson famously starred as Summer Roberts on The O.C. from 2003 to 2007, during which she sparked a three-year romance with Brody, who played her onscreen love interest. After Bilson and Brody's 2006 breakup, she moved on with Hayden Christensen. (Brody, now 47, has since married fellow actress Leighton Meester.) "We met [filming] a movie together," Bilson said of dating Christensen, now 44. "There was a lot more privacy, I felt, like, in that second relationship than the first." Bilson and Christensen welcomed their daughter, Briar Rose, in 2014, nearly three years before going their separate ways.

MORE: Rachel Bilson Gives a Dating Update When grilled by podcast host Kristin Cavallari about whether she is in a relationship, Bilson succinctly stated that she isn't currently dating. "I've never been on [a dating] app, but if I'm around someone who's on it, I look with them 'cause it's fun," she said. "I've never done the apps. I'm a hardcore, like, 'bedtime before 9' kind of person, so if I'm going to go out, it has to be something I really want to do." Bilson, who has never been married, also remains on the fence about whether she'd ever walk down the aisle. "I'm coming into [my] mid-40s, like, [thinking if] I want to do that," Bilson said. "I like how my life is, I don't know." According to Bilson, she also feels that she's "too old" to have another child. "I probably would have, but I don't think my daughter would be down," the Hart of Dixie alum said of Briar. "She's 11 [and] she doesn't want a sibling, she tells me. We have such a thing, I don't want to mess with it. ... She's my little partner [and] she's a buddy, the best buddy." How Rachel Bilson and Hayden Christensen Coparent Briar Bilson gushed on Wednesday that she and Christensen "get along really well" while raising their daughter. "Ours is, like, a unique version of it," she said of their coparenting journey. "We do a lot of stuff together - a lot." According to Bilson, she and Christensen even spend the holidays as a family unit. "We have been able to keep it very copacetic and nice for [Briar]. We weren't ever married so we ... figured out our own way," she said. "[My advice for other coparents] is communication and sometimes you have to compromise a lot." Bilson continued, "I'm really close to his family and it's been almost 19 years or something, which is a long time [ago]. It feels like [water under the bridge]." Bilson also revealed that she and Christensen have been united on certain guidelines for Briar, including when to let their preteen have her own cell phone. "I'm so anti, like, I just want to hold off as long as possible," the actress said. "She's already, like, 'High school?' I'm, like, 'We'll talk.' I just want to hold off as long as possible. ... Her and her dad and I are pretty aligned on all that stuff, so that's helpful. Hopefully it stays that way because I really want to hold off." Lessons Learned From Dating at a Young Age Bilson and Christensen dated on and off from 2007 to 2017. "I was so young. I was 25 when we met, but he and I are the same age," Bilson, who was even briefly engaged to Christensen, said. "I was really young, and I think that relationship let me take a step back. I felt I was very present because I wasn't chasing the career thing. It wasn't No. 1 for me, but I tend to do that. I tend to put relationships - but now my kid - first." Regardless of her young love story, Bilson has "no regrets" with the way the relationship played out. "I think that it was just interesting to see that I put everything else on hold because I wanted to support and nurture that relationship," she acknowledged. "You just change so much [in your early 20s]. You watch The Bachelor and there's girls on there [who are] 23, and I'm, like, 'Don't do it!'"
