"The Situation" is dealing with a serious situation of his own reportedly.

Jersey Shore star Mike "The Situation" Sorrentino is currently in rehab for a substance abuse problem, TMZ reported Tuesday evening.

"[Sorrentino] has checked into an inpatient treatment program," according to TMZ, which did not provide any additional details on what substances the Jersey Star star is being treated for or identify the substance abuse facility that is treating him.

A Sorrentino representative declined to confirm the Jersey Star star is in rehab when contacted by TMZ.  Instead, the rep stated Sorrentino "has spent the past several weeks at an undisclosed location for much needed rest and recuperation after his extensive production and appearance schedule."

Sorrentino's rehab report comes one day after MTV confirmed Jersey Shore will return for a sixth season which will film in Seaside Heights, NJ this summer and expected to feature the show's entire cast -- including pregnant castmember Nicole "Snooki" Polizzi.

"America's favorite housemates will all return to their home-away-from-home, and the house dynamic is headed into unchartered territory... as their lives outside the 'Shore' take off in exciting new directions. While things will definitely be a little different this time when they hit the boardwalk, their trademark hilarity and family dysfunction will remain the same," the network stated in a press release announcing Jersey Shore's sixth season.
