Jon Hamm hosted an event for luxury watch company Jaeger-LeCoultre with his girlfriend Jennifer Westfeldt in NYC on Tuesday night. He's back in the states following a trip to Cannes where he promoted Mad Men alongside costar Elisabeth Moss. We'll have to wait until Sunday to see how things end for womanizing Don Draper on the TV drama's season finale, but he'll be on the small screen tonight as one of Liz Lemon's many love interests for the live episode of 30 Rock. The cast and special guests, which also includes Matt Damon as airplane pilot Carol, will perform once for the East Coast and once for the West.
