Bristol Palin is fuming after Kathy Griffin made fun of her appearance while hosting VH1 Divas Salute the Troops on Friday.

Clad in a bikini, the 50-year-old comedienne joked that the Dancing With the Stars alum "is "the only contestant in the history of the show to actually gain weight" — but Griffin's jibes elicited booing instead of laughter.

"Come on, come on. She gained like 30 pounds a week," Griffin shouted over the crowd. "I swear to God, it was fantastic. She's like the white Precious."

Instead of devising a lengthy comeback — as she did on Saturday after Margaret Cho accused her mother, Sarah Palin, of forcing her to join DWTS — the teen mom kept her rebuttal short and sweet.

"The audience's reaction to this 'comedian' spoke volumes, and the decent people I know would probably have booed her, too," Palin, 20, told Fox News. "I hope people didn't have to pay money to hear her negativity and criticisms."
