Rebecca Romijn only has 30 more days to go before she's officially over the hill. The actress and supermodel, 39, spoke to Us Weekly about the milestone birthday during the Third Annual Veuve Clicquot Polo Classic in L.A.'s Pacific Palisades October 6.

"It's funny: All year long I kept saying, 'I think I want to do a really big party,' and the closer you get to it, I don't really feel like celebrating," the Ugly Betty alum said. "I loved my thirties! It's not like I'm not looking forward to 40; I'm just sad to be leaving my thirties."
