Actor John Goodman showed off his new slim figure on the red carpet of the 38th Annual AFI Life Achievement Award tribute to honor director Mike Nichols Thursday (Jun 10) in Culver City, CA.

Goodman, who rose to fame as “Dan Conner” in the popular 80’s and 90’s sitcom “Roseanne,” is said to have lost over 100 pounds but that’s just a rough estimate. His rep didn’t confirm a specific number, but told USA Today that he achieved his massive weight loss through “diet and exercise.”

Good for him!

Goodman, who will celebrate his 58th birthday in a couple of weeks (Sun. Jun 20), stars in one of HBO‘s newest series “Treme.”
