Howard Stern Sidekick Artie Lange Hospitalized

ET confirms that comedian Artie Lange, one of radio icon Howard Stern's on-air sidekicks, has been hospitalized.

"We can confirm that Artie is in the hospital," a rep for Lange tells us. "Artie has chosen to keep all information on this matter between him and his doctor. There will be no further comment."

Lange was absent from Stern's Sirius-XM radio program in the days leading up to the show's two-week holiday break. The show is scheduled to return live on Monday.
