Kyle Massey's the latest celebrity to endorse the weight-loss benefits of appearing on 'Dancing With the Stars.'

Unlike fellow semi-finalist Bristol Palin -- who's previously said she hasn't lost any weight through being on the show -- Kyle says he's dropped 18 pounds and lost a whopping eight inches off his waist thanks to the punishing regime.

And in an interview with People magazine, the Disney Channel star says he's loving it. His dancing partner, Lacey Schwimmer, joked that " He looks in the mirror all the time."

Kyle attributes his new, leaner physique to the training schedule on the show: "It's crazy to think you're going to come into a competition like this and not lose weight with the hours you're going to have to put in. ... I know I'm going to keep losing weight as long as I'm on this show."

Kyle's hard work is also paying off on the dance floor. After scoring a near-perfect 58 out of 60 in last night's semi-finals, the judges praised his style and star quality. Carrie Ann Inaba even said he reminded her of Season 3 winner, Emmitt Smith.

So will he go all the way to the final, like the 'DWTS' weight loss poster boy from Season 1, John O'Hurley? Tune in for the results show tonight to see if Kyle's winning/losing streak continues.

'Dancing With the Stars' airs Mondays, 8PM ET on ABC. Results show airs Tuesdays, 9PM ET on ABC.
