Rachel Bilson is spotted in Paris Tuesday on the set of a commercial for Magnum ice cream (Mar. 15). Bilson will play a ballerina in the commercial (she was wearing ballet slippers and a tutu under her robe). The shoot was directed by famed German designer Karl Lagerfield.
Even though Rachel has such a youthful look, she's actually turning 30 this year. The actress - who begins production soon on her new CW pilot Hart of Dixie - told Madison that she's a little freaked out:
"I am sort of freaking out. I thought I wasn't going to, but a lot of my friends are a couple of years older than me and they're not helping! They keep saying, 'You’re next'. So I keep saying, 'What’s going to change? Will I implode or something?' My 20s have been good to me, I have to say."
