JENNIFER ANISTON is apparently set to return to the small screen, making a guest appearance on comedy 30 Rock.

Various sources, including America's OK! magazine and Entertainment Tonight, report the star is scheduled to begin filming her role any day now.

There's no word on the character Jen will play in the show, which is a behind-the-scenes spoof of a TV network.

Jennifer's stint as Rachel in Friends finished after 10 seasons in 2004. The actress has only made one TV appearance since then – in FX series Dirt, alongside former Friends co-star COURTENEY COX.
