TMZ Update: Lopez Idol deal imminent

LOS ANGELES (TMZ) - In today's TMZ Update, Jennifer Lopez is in the final stages of negotiations with "American Idol" -- and we're told it's all but a done deal and Jennifer will be the last critical link in the chain.

Sources connected to the negotiations tell TMZ ... contrary to some news reports ... there has been no drama and no diva demands. As one source puts it, "It's been typical negotiating."

Plus, TMZ has learned ... federal officials are "in the process" of determining if they will try to revoke T.I.'s probation in the wake of his arrest late last night.

As TMZ first reported, T.I. -- who is still on probation for illegally possessing machine guns a few years ago -- was arrested again last night for possession of a controlled substance on the Sunset Strip.

Now, United States Attorney Sally Quillian Yates tells TMZ, "The probation office is in the process of determining what happened and will make a recommendation regarding Mr. Harris when they have all the facts."

If officials determine T.I. did violate his probation, he could be sent back to the slammer to serve some serious prison time.
