NW attributes the lesbian rumors plaguing Jessica to her muscular physique and low-key lifestyle. A source says, "The gay rumors keep following Jess, even though she's dating the coolest guy in show biz. 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."

Jessica has become convinced that the rumors were started by a rival, jealous of her success. One snitch says, "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. Jessica is upset, she's wondering where all these rumors 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."

Once Biel discovers who has been spreading the rumor, she plans to show her who’s boss. Says an insider, "Jessica's not sure what she's going to do to stop the same-sex rumors, but she says she's determined to find out who's spreading them and then she's going to kick her ass. She wants some revenge."
