Joan Rivers Reignites Aguilera “Fatso” Feud on Fallon

However, things got a little dicey when the topic of Joan’s feud with Christina Aguilera was brought up. Rivers launched into a tirade that was none too friendly.

She began, “I’m at Spago with Melissa and we’re eating dinner and ‘fatso’ is across the way. And she comes lumbering over with that no-neck look, and I go, ‘Here it comes.’”

“And she comes over to my table and she says, ‘Are you gonna finish that?’” Rivers blurted out with a cackle.
