.: Holly Marie Combs, 30 :.

Star Slimdown

April 2004: "Forty pounds is an awful lot when you're five-two!" Combs says.

The charmed star has dropped most of her pregnancy pounds since delivering son Finley on April 26. But there's still work to be done. "I've the weight, but there's no muscle tone!" Combs complains to Us. "I used to have a nice round butt-where is it?!"

HER SLIM-DOWN SECRET "I'd be lying if I didn't say it was just working on the show and breast-feeding," She says.

EXPERT TAKE "Bouncing back is often genetics," says Michaels. "But weights would help her tone up."
