GQ July 2007 covergirl Jessica Biel is being forced to deny dish that she’s a lesbian in spite of her seemingly passionate affair with Justin Timberlake. The rumors seem to have been sparked by the star’s previously quiet love-life and her ‘muscular figure.’

Lesbian rumors claim that she’s only dating him to deflect attention from her true sexuality.

“The gay rumours keep following Jess, even though she’s dating the coolest guy in show biz,” says a celebrity snoop. “Although she’s seeing Justin, that doesn’t seem to be killing the lesbian buzz surrounding her. Even pictures of her kissing Justin haven’t stopped the chatter.”

According to NW Magazine:

The twenty-five year old is really upset by the ridiculous rumours and has even started to wonder if the whispers have been spread by jealous rivals. She’s certainly noticed the way questions about her sexuality have grown more persistent since she snagged Justin at the Golden Globe Awards earlier this year.

“Jessica thinks plenty of girls are jealous of her because of her suddenly super-hot career, her amazing body and, of course, her red-hot romance with Justin,” says a J.B snoop.

“Jessica is upset, she’s wondering where all these rumours got started. She’s even starting to point the finger at one of Justin’s ex-girlfriends — either Cameron Diaz, Scarlett Johansson or Britney Spears.”

“Jessica’s not sure what she’s going to do to stop the same-sex rumours, but she says she’s determined to find out who’s spreading them and then she’s going to kick her ass,” a friend tells NW. “She wants some revenge.”
