Has Justin Ever Heard Jessica Sing?

A new book exposes the successes—and failures—of celebs like Jessica Biel in the world of a cappella music

Does Justin Timberlake know that his girlfriend, Jessica Biel, once tried to make it as a singer?

Sadly, however, Biel didn’t get far—at least not in college.

The sexy starlet was rejected for a spot with the Amalgamates, an a cappella group at Tufts University, according to GQ senior editor Mickey Rapkin’s new book, Pitch Perfect: A Quest for Collegiate A Cappella Glory.

“The Mates focus on blending in our auditions,” one unnamed “Mate” says. “She wasn’t very good at it…We are kicking ourselves, in case you’re wondering.”

Also kicking himself is Friday Night Lights star Scott Porter. The hottie who plays Jason Street on the hit NBC series tells Rapkin he has some big-time regrets about leaving professional a cappella group Mosaic when he decided to take a shot at Hollywood—especially when he learned Mosaic snagged the opening-act gig for Prince during a New Year’s Eve concert.

“That’s a rock star moment,” Porter says. “I am on this massive amazing TV show that everyone loves, but I devoted eight years of my life to taking the next step with a cappella music.”

And if you think a cappella isn’t hip, Masi Oka of Heroes fame just gave you some more ammunition.

He admits that he once wore a purple leotard and a tutu while singing an a cappella version of “Flashdance” with the all-male Bear Necessities at Brown University. The rest of the group “chickened out and wore leg warmers and bandannas,” Oka says. “But I thought we had to go all out. A cappella is all about commitment.”

Perhaps Oka will be asked to re-create his tutu drama when Pitch Perfect is made into a movie. Elizabeth Banks' production company recently optioned the film rights.
