Setting the dinner table for two and the JOAN RIVERS calls the XTINA AGUILERA a fatso.

Oh dear official.

The comedy legend was on the Jimmy Fallon show to promote her new book when she managed to hurl an insult in the AGUILERA‘s extension.

I’m at Spago’s with [my daughter] 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.’ She comes over to my table and says, ‘You gonna finish that?’

Skip to the (approx) three minutes mark for the visual insult.

Which reminds me of that time the XTINA went through Burger King on MTV Diary and ordered enough food to feed four of me.

Back then I was bicurious as to how she consumed all that and not get fats, guess it all caught up with her innit.
