Jennie Garth dances with idea of baby #4

Jennie Garth, formerly known as Kelly Taylor on FOX's 90210 and current contestant on ABCs Dancing with the Stars, has whipped her body into tip-top shape with all her recent fancy footwork.

"I've lost weight and I'm looking great," she says.

She may not keep her slimmed-down figure for long, though, because she's pretty sure she'll have another baby.

Garth, wife of actor Peter Facinelli and mom to three young daughters, says she secretly looks forward to being pregnant again. Why? "So that she could eat and have ice cream," says her hubby.

Before she focuses on family, Garth, 35, must first finish her ballroom competition. It's down to five dancing couples. Could Garth win it all?
