Jen Returning to NBC?

It's been more than four years since Jennifer Aniston and the cast of Friends said goodbye to adoring TV audiences around the world. But OK! has learned that Jen is in talks with NBC to make a brief return to the network that made her famous.

"She's in talks to have a guest spot on one of their high-profile shows," says the insider. "The top choice is 30 Rock, but if that doesn't work out, they'll try to find another show for her to make an appearance on."

A rep for NBC told OK! they were unable to confirm the story at this time.

This news comes on the heels of Jen's meeting with legendary director Woody Allen, who showed the actress some scenes from an upcoming film over dinner on Monday in L.A..

Of course, with four movies coming up — Management with Steve Zahn, Marley & Me with Owen Wilson, the star-studded film version of the hit book He's Just Not That Into You, and Traveling with Aaron Eckhart —  Jen might already be the hardest working woman in Hollywood.
