"The Situation" is in rehab for substance abuse ... TMZ has learned.
Sources tell TMZ the "Jersey Shore" star -- aka Mike Sorrentino -- has checked into an inpatient treatment program.
A rep for the Situation just contacted TMZ to say they are not confirming that Mike is in rehab ... just that he "has spent the past several weeks at an undisclosed location for much needed rest and recuperation after his extensive production and appearance schedule."
Like most of the 'JS' crew ... Sorrentino's been on a non-stop party train since the show debuted on MTV 2 years ago -- drinking and making paid appearances at nightclubs all over the world.
Sitch makes anywhere from 15K ... up to a whopping 50k per nightclub appearance.
MTV just announced "Jersey Shore" is returning for a 6th season ... which is scheduled to start shooting this summer.
1:10 PM PT -- The Situation is currently undergoing treatment for prescription pills at the famous Cirque Lodge in Utah.
