This. Is. Adorbs. Not only have Rachel Bilson and Hayden Christensen welcomed a little baby girl into the world, they've given her the cutest princess name ever. The Hart Of Dixie and The O.C. star named her daughter Briar Rose, which is the nickname for Princess Aurora from Sleeping Beauty. Sigh. We are srsly loving the Disney vibes of late. After all, Ryan and Eva named their little princess Esmeralda (hello, Hunchback of Notre-Dame). We hope they all live happily ever after.
