Rachel Bilson is a new mom

Actress Rachel Bilson is a new mom after giving birth to baby girl Briar Rose.

The former The O.C. star and her boyfriend, Star Wars actor Hayden Christensen, appear to have picked the fairytale name from the Brothers Grimm's Sleeping Beauty tale. Briar Rose was also the alter ego given to Princess Aurora by her three fairy guardians in the beloved animated Disney film adaptation.

Bilson celebrated the impending birth with a baby shower at the end of August (14) and guests included Hollywood moms Natalie Portman and Jaime King.
