Jon Hamm at the SAG Awards 2013 (Pictures)

Jon Hamm heated up the red carpet at the 2013 SAG Awards when he arrived in a tux. He walked the red carpet with his longtime girlfriend, Jennifer Westfeldt, who wore a sleek Blumarine gown. Jon has some big things to look forward to tonight; he is nominated for outstanding performance by a male actor in a drama series and outstanding performance by an ensemble in a drama series with his fellow castmates for Mad Men. Jon has been nominated for both awards over the past five years but has only won two SAGs — one in 2009 and the other in 2010 — for outstanding performance by an ensemble.
