Mike 'The Situation' Sorrentino: I'm not in rehab!

Mike Sorrentino claims there's no rehab "Situation" going on right now.

The "Jersey Shore" party boy Wednesday shot down reports that he's in rehab for substance abuse issues - rumors that were not exactly surprising considering the massive amounts of booze he chugs down on the MTV show.

Nonetheless, the reality star, 29, wrote on his website Wednesday: "You can't believe everything you hear."

His rep also denied the treatment claims, but did tell TMZ.com the Sitch "has spent the past several weeks at an undisclosed location for much-needed rest and recuperation."

Meanwhile, Sorrentino's ex-"Shore" roommate Angelina Pivnarik chimed in Wednesday, telling radio's "Murphy in the Morning Show" that she isn't surprised by the rehab vreports because Sorrentino has been doing drugs for years.
