Jersey Shore star Ronnie Ortiz-Magro has been hospitalized due to kidney stones.

The reality star, who is still dating Sammi “Sweetheart” Giancola after meeting her on the hit MTV show, has been tweeting about being in the hospital.

Not long after writing that he was in Florida to promote his alcohol line, Smush Cocktail, he wrote "Wouldn't wish this feeling on anyone! Kidneys. FML."

He simply stated before that, “Hospital.”

His rep also confirmed to Us Weekly that he was in the hospital, and told People, "Ronnie was admitted to an Orlando area hospital late Saturday night. He's in a lot of pain and is expected to remain there for several days."

"It's a very painful condition, but he's being treated,” the rep continued.

Ortiz-Magro, 27, also went on to tell a fan who suggested he drink some protein, “I have to because I can't hold any food down from the pain." He added, "Worst feeling. So uncomfortable."
