Patti Lupone Rocks TGS

Stage legend Patti Lupone will be guest starring on another New York based comedy this year.

The actress who appeared on Ugly Betty as the mother of  Marc St. James in 2007, will be playing mum once again, but this time to Judah Friedlander’s character Frank Rossitano on 30 Rock.

So we’ve already seen Jack’s mother and now Frank’s. Next feat will be seeing who they cast as Liz Lemon’s mum on the hilarious NBC comedy. Now those will be interesting shoes to fill…

Who do you think?
