Winter may be just around the corner, but the stars of the small screen just keep getting hotter, and in cumulative fashion. When it comes to the steamy factor, we've put together our picks for the shows with casts who sizzle at the highest temperatures, and want to know how you weigh in. (Speaking of "steamy," 'Grey's Anatomy' didn't make the cut! Sorry, kids!) We went for all age ranges, from the young and sexy city guys and gals of 'Gossip Girl' to the sophisticated and classy 'Mad Men' crew, plus a few personal favorites that we think deserve to be in the sexy elite. So huddle in close and after the jump, read why we picked these shows and then pick TV's sexiest cast.
