Charles Barkley's endorsement of Watch Watchers has already helped slim his waistline; now he's crossing gender lines.

In the new "Lose Like A Man" advertisement for the weight loss program set to air in April, Barkley will don a black dress, a wig, earrings, a bracelet, a pinky ring and black heels to help impart the message that Weight Watchers isn't just for women.

Barkley, a Basketball Hall of Famer now serving as an NBA commentator for TNT, has now lost 42 pounds since he began using the program, according to the company.

Back in January, Barkley was caught on a live mic joking that his Weight Watchers endorsement is a "scam" because he was being paid to lose weight.

Weight Watchers later issued a statement from Barkley that read: "I meant what I said, the fact that I’m dropping pounds, getting healthier and getting paid at the same time, is my definition of a great scam," Barkley's statement read. "The only problem is I’m going to have to use some of the money to buy a new wardrobe."

Is cross-dressing what he meant by a new wardrobe? Scroll down and soak in the sight for yourself.
