Get ready for season five!
Mad Men is back! Well, almost, anyway.

The stars of the Emmy-winning AMC series arrived in Hollywood last night for the show’s long-awaited season 5 premiere, held at the famous ArcLight theater.

Naturally, all eyes were on the show’s biggest A-listers, January Jones and Jon Hamm, who looked hotter than ever. January wore a top and skirt by Roland Mouret, while Jon Hamm looked dapper as usual in a Don Draper-esque suit. (His partner, Friends With Kids star-writer Jennifer Westfeldt, wore a green dress by Kate Spade New York.)

Mad Men returns with a two-hour premiere on March 25.

Celebuzz was on the scene at last night’s Mad Men premiere. We’ll have the full scoop, including interviews with the stars of the show, a bit later today. In the meantime, check out the cast’s red-hot arrival in our gallery!
