UPDATE: Bristol has responded to Kathy's comments in a statement to Fox News' Pop Tarts:
"The audience's reaction to this 'comedian' spoke volumes, and the decent people I know would probably have booed her, too. I hope people didn't have to pay money to hear her negativity and criticisms."
PREVIOUSLY: Kathy Griffin showed off her starvation body in a bikini at the VH1 Divas Salute the Troops concert Friday night, and during her opening monologue she called Bristol Palin fat.
"She's the only contestant in the history of the show to actually gain weight," Kathy said of Bristol's long run on 'Dancing With the Stars' as the troops loudly booed.
"No, come on, come on," she continued. "She gained like 30 pounds a week, I swear to God, it was fantastic. She's like the white Precious."
