TORI SPELLING BACK IN TALKS WITH 90210

Jennie Garth's Kelly Taylor has been a fixture on the CW's 90210; Shannen Doherty's Brenda Walsh has done a few drive-bys. Even Jason Priestley is stopping by to step behind the camera.

So who's next? Sources tell me producers are actively working once more on getting Tori Spelling on screen as Donna Martin before season's end for a multiple-episode arc.

So will it happen? And what's this about a Luke Perry lookalike (gasp!) cozying up to Naomi?
