UPDATE: Phew. One Direction's PR company addressed rumors, stating: "It’s completely untrue, Zayn isn’t leaving the band."

Uh oh, Directioners. Rumor has it Zayn Malik may want to leave One Direction. Why would he drop the chance to be in one of the biggest pop acts on the planet right now at their peak?

Celebuzz reports that after that Aussie waitress sold her cheating story -- and photos of a sleeping Malik -- to a tabloid, the singer has become increasingly withdrawn and reluctant to pursue fame anymore. Malik was reportedly "rocked to his core" when the news broke of his tryst behind Little Mix singer Perrie Edwards' back, but that his issues started earlier than that.

This isn't the first time rumors that Malik may leave have emerged, either. Back in August, professional troll, bottom feeder and cyber bully Perez Hilton posted a video of what appeared to be Malik inviting a girl -- not Edwards -- back to his hotel, leading the singer to quit Twitter and to rumors that he would be the first to leave the band.

Sources say Malik comes from a super tight-knit family, and he hates being away from them for long. With a world tour and a 3D movie to promote in the very near future, that's going to prove difficult for the token bad boy. As a result, the band's management has even offered Malik a little extra time off.

An insider said, "There is growing concern among the bosses that Zayn is on the brink at the moment.”

Still, all hope isn't lost: Every member of One Direction recently signed a three-year contract, so we may have Zayn with us whether he likes it or not.
