Love may be in the air for Liz Lemon (Tina Fey) on the NBC comedy "30 Rock," so which star has the show tapped as the man to "Rock" Tina's world?

Jon Hamm, of AMC's drama "Mad Men," will be guest-starring as Tina's new love interest, the Associated Press says.

The question remains will Hamm continue to appear on the show.

"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 AP. "And then we'll see what happens."

The Golden Globe winner plays an advertising exec. on "Mad Men," but will be cast as doctor who lives in Liz Lemon's apartment building.

Be sure to catch "30 Rock" Thursday nights on NBC.

Okay, first of all, I love Jon Hamm. A whole lot. But is anyone else a little sick of/concerned by the excessive guest stars this season? 30 Rock seems solid enough in ratings that it doesn't have to bring in so many famous people; is it just worried because of Arrested Development and co.?

I wrote more about that here, if anyone feels like reading more: http://www.fanforum.com/f240/superbowl-episode-62875392/

But thoughts?
