OTRC: Joan Rivers slams Sarah Palin, Fox News

Joan Rivers, 77, speaks to OnTheRedCarpet.com in May 2010 about her documentary, 'Joan Rivers: A Piece of Work.'

Joan Rivers says negative comments she made about Sarah Palin prompted Fox News to cancel her scheduled appearance on its show "Fox and Friends," although the cable network denies this.

The 77-year-old comedienne said in a video posted on TMZ that Palin, the former Republican governor of Alaska who is seen as a likely 2012 presidential candidate, was "just stupid and a threat" and added she agreed with those who blamed the politician for the recent shooting of Arizona congresswoman, Gabrielle Giffords.

"While @melrivers and I were promoting our new @wetv reality show, I made a joke about Sarah Palin that was picked up by @TMZ," Rivers said on her Twitter page on Wednesday, referring to her daughter and co-star Melissa. "As a result, our appearance on the Fox News Channel tomorrow morning has been cancelled."

Palin, the former governor of Alaska who is seen as a likely 2012 presidential candidate, has not responded. Rivers' new reality show, "Joan & Melissa: Joan Knows Best," is set to debut on WEtv on January 25.

"Due to the volume of news topics tomorrow morning and a full show, our booker mistakenly canceled Joan's appearance instead of re-scheduling her for Friday's show," Us Weekly quoted "Fox and Friends" executive producer Lauren Petterson as saying in a statement. "We're in the process of booking her on an upcoming show."

"Now we call it "Fox and Former Friends,'" Rivers said on HLN's "The Joy Behar Show" on Wednesday. "They said to our PR lady, she said, 'Why' and they said, 'Because of what was said about Ms. Palin.'

Rivers also slammed Palin's daughter Bristol, who placed third on "Dancing With the Stars" in the fall of 2010 and faced criticism by viewers who felt she was not as good as many contestants who were eliminated beforehand. "I voted for her stupid daughter, who couldn't dance at all," Rivers told Behar. "I felt sorry for her."
