Reality TV star Ronnie Ortiz-Magro has been hospitalized in Orlando, Florida, and is being treated for kidney stones.

The Jersey Shore star was admitted on Saturday night and is expected to remain there for a few days.

"Ronnie was admitted to an Orlando area hospital late Saturday night," the star's rep told "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."

Ronnie was promoting his new line of "Smush Cocktails" at a liquor convention when he "started feeling uncomfortable."

Sunday morning Ronnie tweeted about his pain. "Hospital... Wouldn't wish this feeling on anyone!" He wrote.
