Rachel Bilson and ex Hayden Christensen's daughter Briar Rose has a name fit for a princess.

The O.C. alum, 40, recently shared how she and the Stars Wars actor, 41, chose their 7-year-old's name.

"So, when I was pregnant," she began on the Aug. 22 episode of her Broad Ideas podcast, "we really were stuck on Millie and then the more we thought about it—cause Hayden and I met in a movie called Jumper and my character's name was Millie—and then we couldn't decide if that's like super lame or super cute."
