Cosmo: Katherine Heigl's Prettiest Cover

Cosmo always makes the stars look sexy and at their best.   Katherine Heigl, who has been on a ton of covers lately,  never looked better! There’s another reason why Cosmo is the number one women’s magazine:  Great cover lines developed by Editor-in-Chief Kate White!.   “Arouse Him Like Crazy!,”  “Great Butt and Thighs,” and “The Most Satisfying Sex Position.”  Plus, the almost hidden gem – John Mayer – “Shares Why All Guys Aren’t A**holes.”
