speidilogo.jpgHeidi Montag is still suing The Hills’ executive producer Adam Divello for sexual assault contrary to online reports claiming the lawsuit has been dropped.

Sources close to the couple tell X17online exclusively that "the lawsuit is 100% on." In the lawsuit, Montag claims Divello touched her butt cheeks and stomach on the set of MTV's The Hills.

Our source adds, "Heidi still feels that Adam acted inappropriately as a producer. He wasn't professional on the set."

MTV claims the lawsuit against Divello is "completely false and without merit."

As X17online first reported, the relationship between The Pratts and MTV is beyond strained. Our source says:

    "MTV has been asking Heidi to shoot scenes for the last couple episodes of The Hills, and she's been declining. She's trying her hardest to film as little as possible. Part of her wants to make it difficult for them."


MTV hasn't been asking Spencer to film any episodes lately. "MTV still owes him money for past episodes, and Spencer doesn't exactly get along with the show's producers," adds our source.

Heidi's rep says "no comment."

Sounds like the drama off-camera is better than what's being caught on tape!
