Love is in the air for 30 Rock’s Liz Lemon.

Jon Hamm, of AMC’s critically-acclaimed drama Mad Men, will be guest-starring as the new love interest of Tina Fey’s television producing alter ego on the Emmy-winning NBC series.

“I just finished a couple of episodes, and I’ll go back in the new year and do another one of those,” Jon tells the Associated Press. “And then we’ll see what happens.”

Jon will be cast as doctor who lives in Liz’s apartment building.
