January Jones is a blonde waif with a meaty pair and a penchant to show them off with revealing wardrobes that usually stop just short of skin. She made her film debut in the indie All the Rage (1999) and followed that up with a small role in the teen thriller The Glass House (2001). Her supporting role in Full Frontal (2002) was not nearly as revealing as it sounds, though she did heat up the Adam Sandler/Jack Nicholson comedy Anger Management (2003) playing a lesbian porno star. Wonder if she did any deep research for that part? Her highest-profile gigs to date were as Alyson Hannigan's hot sister in the third installment of the great American Pie series, American Wedding (2003), and in Dirty Dancing: Havana Nights (2004), not to mention her role as sex kitten Betty on the smash series Mad Men. But she was her dirtiest in The Three Burials of Melquaides Estrada (2005), surreptitiously slipping a bit of nip. Contrary to popular belief, January is the hottest month!
