What were Jessica Biel’s plans for her 25th birthday Saturday? “This!” she told PEOPLE at a party in Paris for designer Giambattista Valli, whose show she attended.
“I’m in Paris with my friends. Just being here is enough,” said Biel, who arrived with two female pals shortly after 11 p.m. at the Salons France Ameriques and went straight to the VIP room.
At the Valli party, Biel and her friends sipped champagne and chatted until 1:30 a.m., when a chocolate cake with a sparkler was brought out. “Happy Birthday Jessica” was written on the cake in icing.
Biel – dressed in a strapless black, white and yellow Valli dress that had appeared on the runway – clapped her hands, hugged Valli, and happily took a piece of cake, declaring: “I’m not one of those skinny actors. I’ve got meat on my bones.”
Other guests at the party included Mary-Kate and Ashley Olsen and supermodels Jessica Stam, Daria Werbowy, and Gemma Ward.
Biel, who arrived in Paris last Tuesday and attended several fashion shows, partied until 2:30 a.m. before calling it a night.
