Who knew? Dan from Roseanne out of rehab

John Goodman has checked out of rehab after being treated for an "undisclosed reason."

Entertainment Tonight reported yesterday the actor has checked out of Promises Treatment Center in Malibu.

"For my family and myself, I voluntarily took the necessary steps to remain sober the rest of my life," Goodman said in a statement issued by his publicist Stan Rosenfield.

It was unclear how long Goodman was in rehab, or when he was released.

Goodman, now 55, is best known for playing Dan Conner on the hit sitcom "Roseanne" in the 1980's and 90's. His film credits include "The Big Lebowski," "The Flintstones" and "The Babe."
