Cher's son has struggled with his weight for the last several years but he's discovering the added bonus of being a DWTS contestant -- weight loss!

Kirstie Alley, Kelly Osbourne and Marie Osmond are just a few of the celebs who reported considerable weight loss, thanks to all those extra hours of work-outs during their time on the hit ABC show.

Chaz appears to already be down at least 20 pounds since prior to his being cast for the show, and he still has two weeks to go before season 13 premieres September 19.

Weigh to go, Chaz!
