Mike "The Situation" Sorrentino has checked into rehab to deal with an addiction to prescription pills, but his former Jersey Shore castmate dropped the bombshell accusation Wednesday that the reality star has been doing drugs for years.

"I don't understand how nobody caught on to him doing a mass amount of drugs!" Angelina Pivarnik told the Murphy in the Morning Show about her former co-star, who has entered rehab to treat his addictions.

"Obviously he's been using the money not for charity, and stuff like that to help kids out, to help people that are less fortunate, but using blow," the Jersey Shore castoff said.

There is no love lost between Angelina, who was booted off the show after the second season, and her former co-stars.

"He's hideous!" she said about Mike, whom she calls "Popeye on crack."

"He deserves to freakin' stay in rehab for the next 10 years! Please stay in the rehab and don't come out!"
