Jon Hamm and Stars at Mad Men's Season Six Premiere | Photos

Last night, the stars of Mad Men previewed the first episode of the upcoming sixth season for a VIP crowd at the Directors Guild of America's LA theater. Jon Hamm, January Jones, Christina Hendricks, and Elisabeth Moss were among the cast members who turned up for the premiere, but there was more than just a new season to celebrate. Their costar Vincent Kartheiser and Alexis Bledel, who had an arc on the show last season, just announced they are engaged! When we caught up with Jon last evening, he told us most of the cast has known about the happy news for a while and are all glad to be able to celebrate it publicly now. Jon attended the premiere with his longtime love, Jennifer Westfeldt, and Christina was joined by her husband, Geoffrey Arend, but Vincent appeared to arrive solo to the screening.

The Mad Men cast and the show's creator, Matthew Weiner, are notoriously tight-lipped about the plot. Still, they assured us that this season of Mad Men, which premieres on April 7, is worth tuning in for. Matthew spoke to us about Jon reprising his role as a director in 2013, Jon told us how portraying Don Draper has changed his life, and Elisabeth Moss talked about what it was like to transition from her 20s to her 30s on screen.
