Rachel Bilson is all about spending time with her favorite girl — her daughter Briar Rose.

While speaking to PEOPLE at the launch party for the new The O.C. x 21Seeds “Serving Summer” campaign in Los Angeles on Wednesday, July 31, the actress, 42, chatted about her 9-year-old and gave rare insight into their mother-daughter relationship as she looks forward to Briar's 10th birthday in October.

"Oh, my god, it's crazy. She does not want to get old," the actress says of Briar, whom she shares with ex-husband Hayden Christensen. "She likes being young. She's not one of those kids that just wants to speed it up and have a car and all that."

The O.C. alum also shared that her favorite part about watching Briar grow up is seeing how "kind" she is.

"You know what I love? She is kind and that's the best thing that you can hear or want for your kid," says Bilson. "And even other parents have shared that and that makes me very proud."

The Hart of Dixie alum went on to describe their close-knit mother-daughter relationship, sharing, "It's so crazy, we're pretty inseparable. We have a very, very close relationship. We're not usually ever apart for long."

Bilson continues, "And she talks to me. She is very open and will talk to me about things or what kids say at school or whatever it is, or, 'I felt sad.' It's just really nice that we have that dialogue."

As for how the mother-daughter duo will celebrate Briar hitting double digits, Bilson jokes it's hard to decide when Briar "wants to do everything."

"We've been doing Disneyland as a tradition so we might... I don't know," she says. "She likes everything. That's the problem. We’re so busy because she wants to do everything, every sport, every extracurricular, and that's what we do."

And while Briar is getting older, the proud mom said she's "not even close" to being old enough to watch her mom play Summer in The O.C.

"No. Not at all. Not even close," she laughs, adding that Briar must be "35, maybe 40" to watch.
