With the April 7th premiere of Mad Men's sixth season just around the corner, leading man Jon Hamm graces the cover of the next issue of Rolling Stone, on newsstands and in the iTunes App Store this Friday, March 29th.

Get exclusive behind-the-scenes look at Hamm's poolside cover shoot, as the Mad Men star talks about character Don Draper's good and bad sides, as well as his "tremendous creative streak": "I know he'd probably publish Rolling Stone," he says with a smile. Hamm also speaks his mind on rock & roll's most pressing question: The Beatles or the Rolling Stones? "The Beatles for me are almost like too perfect, they're too clean," Hamm says. "The Rolling Stones have that dirt and grit."
