Rachel Bilson Gives Birth, Welcomes Baby Girl

Congratulations, Rachel Bilson and Hayden Christensen! The actress formerly known as Summer Roberts gave birth to a baby girl today, Us Weekly reports. To continue the tradition of Hollywood actors giving their famous spawn fascinating names, the couple gave their baby girl a Disney princess-themed name - Briar Rose!

The adorable moniker is a nod to the 1959 classic Sleeping Beauty; sheltering Princess Aurora from Maleficent's curse, the three fairies call the little girl Briar Rose. It's also the name that was used in the original Grimm Brothers fairy tale in 1812.
