'Jersey Shore's' Mike 'The Situation' Sorrentino enters rehab

A rep for Sitch tells TMZ that the "Jersey Shore" cast member "has spent the past several weeks at an undisclosed location for much needed rest and recuperation after his extensive production and appearance schedule."

The reality star was apparently been on a non-stop club tour -- banking at least $15,000 per gig -- before his party train derailed.

On Monday (March 19), MTV announced that "Jersey Shore" would be returning for a sixth season that will start shooting in Seaside Heights this summer. Between a sober Situation and a pregnant Snooki, things could start getting real.
