Celebrity Jessica Biel Will Be Jessica Timberlake "I think I really won the jackpot of names," the newlywed tells PEOPLE By Jennifer Garcia Published on October 25, 2012 07:00 PM Share Tweet Pin Email Newlywed Jessica Biel is ready for all the changes that come with married life – including a new last name. “Yes, I’m changing my name,” says Biel, 30, who next appears in the film Hitchcock. “My professional name will still be the same, but for life, yes, I think it sounds great. I think I really won the jackpot of names.” But Biel, who wore a “whimsical” Giambattista Valli Haute Couture gown for her Oct. 19 wedding to Justin Timberlake , is most excited about building a life with her new husband. “It’s hard to find that one person in the world,” says Biel. “Once you find that person, go for it. That kind of commitment is very special.” PHOTOS: Justin & Jessica’s Road to the Altar The stars’ "fantasy" nuptials capped off a week of celebrating for the duo, who toasted alongside 100 close friends and family on the Southern Italian coast.
