Former "Beverly Hills, 90210" star Ian Ziering hit the stage with the shirtless hunks of Chippendales this weekend -- and he definitely got in shape for his role in the show.
The 49-year-old actor will be a guest host for the Las Vegas show Thursdays through Sundays through June 30 at the Rio.
Ziering dropped an impressive 25 pounds in the last three months for the gig -- and was seen working out like crazy -- going from 205 to 180 pounds!
Looks like all that hard work paid off.
