Jennifer Aniston - Super Stalker

Since the end of "Friends," Jennifer Aniston has been a bit like a groundhog.  She pops her head out every once in a while to make a guest appearance in a television show like "Dirt" or to make an indie film like "Derailed" or "Friends With Money."  But other than her personal problems, which the world knows far too much about, it's almost hard to remember how much fun she is to watch onscreen.

"30 Rock" will be curtailing a bit of this problem - if only temporarily.  Aniston will follow in the footsteps of fellow "Friend" David Schwimmer by appearing in a guest spot on Tina Fey's show.  Aniston will appear as Claire, a former roommate of Liz Lemon's has a slight obsessive tendency when it comes to boyfriends.  And the focus of her attention now?  Jack Donaghy (Alec Baldwin).

6 Degrees Fun Fact: Which Schwimmer and Aniston make the "Friends" march to "30 Rock," Baldwin did the march to "Friends" first.  He appeared in an episode of the show as a perky boyfriend of Phoebe's who thought everything in the world was magical... Ah, how times have changed.
