Jennifer Garner, Heidi Klum: When Hot Mothers Attack

Not every celebrity mother is Britney Spears.

Some actually find time to play with their children. And wear underpants. Take the case of the following two beauties:

Jennifer Garner, a first-time mommy, looks like a natural with daughter Violet. We may have questioned this actress' taste when she wedded Ben Affleck, but there's no denying her parental skills. Way to be, Jen.

Then, there's maternal veteran and model, Heidi Klum. Three kids into her marriage to Seal and this knockout is as playful as ever. 

We're guessing Kara Janx, a former finalist on Klum's show, Project Runway, only hopes she and her new husband are equally caring parents someday. Don't we all?
