Heidi Fleiss Calls Tom Sizemore a 'Loser' on 'Celeb Rehab' (VIDEO)

It's heartening to see Mackenzie Phillips – or Mac Attack, as Dennis Rodman calls her – doing really well. "It is amazing that you are standing here today, doing 20 years of these hard, hard drugs," said Rodman, "but you keepin' it together, man."

But not all of the feedback was positive as the celebs came to the end of their stint on 'Celebrity Rehab With Dr. Drew' (Thu., 10PM ET on VH1). Heidi Fleiss looked at Tom Sizemore and said, "Tom, I'm gonna go very easy on you. I look at you, and I feel so good, because you're such a loser. And the thought of bein' with you would turn a woman gay."

Harsh, Heidi. You'd better watch your back, girl. And maybe take a look in the mirror.
