David Spade calls Denise Richards a backstabber

The Denise Richards/Charlie Sheen war just got uglier. David Spade has fired the latest salvo, claiming Richards is a backstabber.

Richards, who has accused Sheen of a laundry list of sins including death threats against her, is apparently romantically involved with Richie Sambora, whose marriage to Heather Locklear is also ending. Locklear and Richards were once close friends, until the 'Spin City' star learned of Richards' relationship with her estranged husband.

Thursday, outside the popular Los Angeles restaurant Koi, Spade, who has been romantically linked to Locklear, was asked how Heather feels about Denise these days. His response, "She's still nursing the knife wound in her back."
