'FABLife': Supermodels, Reality Stars, News Vets In The Running To Replace Tyra

Tyra Banks is replaceable ... at least according to honchos at the "FABLife."

We're told the show's got a long list of celebs -- all with hosting experience -- who are in the running to fill Banks' shoes after her heated and abrupt departure.

The names include Naomi Campbell, Heidi Klum, Christina Milian, Sherri Shepherd, Rocco DiSpirito, Tori Spelling and Kiki Palmer.

We're told there's no frontrunner but most of those on the list have expressed interest.

Our sources say Giuliana Rancic is into the idea and is working with "FABlife" to lock down a guest hosting gig some time soon to test the waters.
