Artie Lange, a.k.a. Howard Stern's sidekick, has been hospitalized in New Jersey.
The 42-year-old former MADtv star was admitted for an undisclosed ailment.
"Artie is in the hospital," Lange's rep said in a statement. "Artie has chosen to keep this matter between him and his doctor. There will be no further comment."
Lange, who has a history of substance-abuse issues, had been MIA from Howard Stern's satellite radio show for a month and canceled several stand-up gigs.
Get well soon, Artie Lange.
He recently pulled the plug on a New Year's Eve engagement, and per his official website, all of his stand-up dates through February have also been scrapped.
In 2009, Artie Lange made headlines for a DUI bust (for prescription sleeping pills) as well as a profane, homophobic appearance on HBO's Joe Buck Live.
While Lange's health situation and Stern fate remain unclear, perhaps Stern will shed light on it when he comes back from his holiday hiatus Monday.
