Joan Rivers pretty much makes a living these days by slamming other celebrities.
Last night, meanwhile, Rivers was a guest on Watch What Happens Live and was asked by a fan which celebrity reacted most negatively to an E! Fashion Police critique.
The worst criticism was Gwyneth Paltrow," Rivers replied. “She came and yelled at us, but she stood up. She can't sit down cause she's got a stick up her rear end."
Okay, that is pretty funny.
Last April, Paltrow was named the Most Beautiful Woman in the World by People, a distinction Rivers said must have been voted on by "Helen Keller and Stevie Wonder."
Simply put, Paltrow is "not my favorite," Rivers concluded.
There actually is a precedent to this feud.
The Goop founder took a jab at Rivers during an interview with Harper's Bazaar last year.
"I've probably tried everything," the 41-year-old told the magazine of cosmetic procedures. "I would be scared to go under the knife, but you know, talk to me when I'm 50. I'll try anything. Except I won't do Botox again, because I looked crazy. I looked like Joan Rivers!"
Paltrow, of course, has other things to worry about these days than anything Joan Rivers does or thinks.
She's consciously uncoupled from Chris Martin and is dealing with fallout from this divorce.
