Tina Fey: It's funny cuz in real life, Jason Sudeikis, my ex-boyfriend on "30 Rock," dates January Jones, your ex-wife on "Mad Men." And yet, we don't date each other IRL. Isn't that weird? Jon Hamm: Tina, have you met my girlfriend, Jennifer? Jennifer Westfeldt: Don't worry, I don't mind. Ladies hit on my boyfriend right in front of me every day of my life.
