Chelsea Handler may have one of the best friendships in Hollywood with actress Jennifer Aniston, but shes got her fair share of A-list haters as well.

The UKs Daily Mail reported comedian and E! Fashion Police co-host Joan Rivers is not a big Handler fan.

The 78-year-old went on Howard Sterns Sirius XM radio show Tuesday and called the E! talk show host a drunk and a whore.

But Rivers wasnt the only one badmouthing funnywomen.

According to the New York Post, Handler was on the show on Monday telling Stern, "What the f--k do I care about Joan Rivers?"

Well it seems Rivers at least cares a little about Handler, claiming the 36-year-old "made it on her back, f--king the president [of E!] ... we all know how she got there."

Handler and Ted Harbert, Comcast Entertainment Groups former CEO, had dated for four years from 2006 to 2010.

"She's fine, she's ordinary, she's not a genius," Rivers added. "She's a drunk. Don't you come after me you whore."

Rivers, who recently made headlines for photos of her makeup-less face, was on the radio show with her daughter, Melissa, promoting their WE reality show, Joan & Melissa: Joan Knows Best?"

The second season of the show premiered Tuesday night.
