Stern sidekick Artie Lange enters rehab

NEW YORK, Aug. 6 (UPI) -- Artie Lange's publicist told E! News the U.S. comedian and Howard Stern's radio-show sidekick has entered an outpatient rehab program.

It is unclear where and for what Lange is being treated.

E! said Lange recently canceled several stand-up gigs and a scheduled appearance on Comedy Central's roast of Bob Saget, which was taped in Los Angeles Sunday night.

Lange reportedly has battled weight issues, and addictions to drugs and alcohol for years.
