Yesterday news broke that Mike "The Situation" Sorrentino was in rehab to deal with his substance abuse issues.  Now reps for the Jersey Shore star are denying the entire story.

For five seasons, The Situation has lived it up.  Partying like there is no tomorrow.  We have even witnessed him lose it at times.  He is constantly fighting with the roommates, he even ran into a concrete wall in Italy.  More recently, he displayed nervous/paranoid behavior while on a camping trip.

But according to people in his camp, that is just him being over worked.  Here is what reps said:

"He has spent the past several weeks at an undisclosed location for much needed rest and recuperation after his extensive production and appearance schedule."

Mike, himself, even denied the rumors through twitter:

"Getting in amazing shape for season 6."  As well as, "Don't believe everything you read or hear."

Hmmm.  Celebs have lied before, but the truth always comes out.  I guess we'll have to wait and see.
