Joan Rivers has skewered Christina Aguilera for her weight yet again, this time making fun of ‘The Voice’ coach on ‘Late Night with Jimmy Fallon.’

The ‘Fashion Police’ star appeared on the late-night talk show to promote her new book, ‘I Hate Everyone, Starting with Me,’ when she launched into an affront on the pop singer.

“Christina Aguilera, we mentioned that she was fat. I think the joke was, ‘Cows tip her,’” Rivers said to Fallon. “So, I’m in a restaurant, I’m in Spagos with Melissa (my daughter), we’re eating dinner and fatso is along the way, she comes lumbering over to my table with that no-neck look, she comes over and says, ‘You gonna finish that?’”

Last year, Rivers criticized Aguilera for looking “like a pig” during her performance at Michael Jackson’s tribute concert, and when the pop star flubbed the National Anthem at Super Bowl, Rivers commented, “How stupid can you get? Christina must have been thinking about food … that’s why she forgot the words.”

Earlier this year, Aguilera defended herself and her weight, saying, ”I’m very confident in my body. I think my video works over the years have spoken to that … I’ve been no stranger to being very comfortable in my own skin.”
