Although it’s been well over a decade since Sarah Michelle Gellar kicked major butt as the titular character in the ’90s series, Buffy the Vampire Slayer, we still look up to the busy mother of two (daughter Charlotte is 4, and son Rocky is 1), who balances motherhood and career flawlessly.

The vampire slayer also landed roles in iconic flicks like I Know What You Did Last Summer (which brought together Gellar and Freddie Prinze Jr. a.k.a. the cutest celebrity couple ever!) and the leading role in Cruel Intentions–could anyone else really play the scheming Kathryn Merteuil as well as she did? We think not!
