Friends of September 2007 Glamour Mag covergirl Jessica Biel are encouraging the big-bootied beauty to give her hero BF Justin Timberlake the boot. Team Biel claims Timberlake is simply too arrogant and moody for their beloved J.B.

“Before Justin, Jess was happy-go-lucky and very independent,” says a source close to the 25-year-old actress. “She would have never chased a guy halfway around the globe like she did with Justin. But he cast a spell over her. Honestly, Jess’ friends don’t get what she sees in him.

J.T and J.B are reportedly shacking up together in L.A and Justin almost never wants to go out with her and her friends.

“He’s arrogant, and his pals adapted to that a long time ago,” says one J.B buddy. “But when new people, like Jessica’s friends, come into the picture, they’re usually turned off by it. When one of Jess’ best girlfriends met Justin for the first time, she was gushing about how much she loved his last album, and Justin said, in all seriousness, to tell him something he hasn’t heard.”

“He acted like it was this girl’s duty to praise him. The worst is that Justin won’t acknowledge his relationship publicly. It’s disrespectful and unmanly to not confirm the obvious.”

“Justin is moody,” says a tab source. “Some days he won’t call Jess, and when she texts him, he says he wants to be alone. Justin is dragging down Jess’ self-esteem, and it’s written all over her face. She doesn’t smile much anymore and she’s lost in the joie de vivre that was her trademark. Justin might be talented as a singer and a musician, but he’s lousy boyfriend material.”
