The (designer) gloves are off!

Yves Saint Laurent may be the highest-earning dead celebrity, but he's not getting much love from designer-turned-director Tom Ford, according to the December/January issue of The Advocate.

In a new interview that's sure to send ol' Yves doing 360s in his grave, Ford -- who won raves and accolades for his work as YSL creative director in the early 2000s -- calls the design legend "evil" and (ouch) "very femmy."

"Being at Yves Saint Laurent was such a negative experience for me even though the business boomed while I was there," Ford told the magazine.

"Yves and his partner, Pierre Bergé, were so difficult and so evil and made my life such misery. I've never talked about this on the record before, but it was an awful time for me.

"Pierre and Yves were just evil. So Yves Saint Laurent doesn't exist for me.

"I have letters from Yves Saint Laurent that are so mean you cannot even believe such vitriol is possible... I just think he was jealous, and Yves and I were friends before I took over the company. But then we began to move the company forward and were very successful...he just became so insanely jealous."

Well, so much for resting in peace. Guess we'll let Ford have the last word on this one because, well...Yves ain't talking.

The juicy interview also features Ford's confession that he uses Botox, plus behind-the-scenes details about his directorial debut, "A Single Man," set to hit theaters in December.

Tom and Yves may have had a rocky relationship, but that doesn't stop the fashion world from getting excited about Ford's upcoming foray into womenswear.
