We already know that Justin Timberlake can sing, dance and act—but does his girlfriend have more than one talent?

Later this summer, Jessica Biel will be taking a break from the small screen to test out her chops in a smaller forum. “I auditioned for a summer production of Guys and Dolls at the Hollywood Bowl. I thought, ‘Well, I’m not a soprano anymore, but I guess I’ll go in for it.’ I literally walked in and said, ‘I can do this song but we’re going to have to drop it down a few notes.’ Actually, I did pretty well and I got the part of Sandy, which I’ll be performing later this summer,” Biel told Parade.

Those unable to make one of those performances can sample Jessica’s vocal abilities in her new film, Easy Virtue. “That just sort of happened in the middle of shooting. The director, who I guess heard me humming or singing along with something, said ‘You have such a great voice. We want to do ‘Mad About the Boy,’ and you should perform it.’ I hadn’t planned on it, but it was just such a treat because I know nobody really knows this about me, but I really started in musical theater doing Annie and The Sound of Music. I wanted to be Whitney Houston. That was my dream,” she explained.

So after listening to her performance, tell us what you think. Does Biel have an appealing voice…or should she stick to her day job?
