Joan Rivers has done it again, slamming Girls star Lena Dunham for sending out the message that it’s OK to be fat.

The 80-year-old comedian, who has never been known to mince her words, has attacked Lena’s weight and fashion sense.

Joan said that while she thought Lena was “terrific”, she didn’t know how she could wear “dresses above the knee.”

The Fashion Police presenter slammed Lena for wearing a bikini during an entire episode in the latest season of Girls, the show Lena herself created.

“You’re sending a message out to people saying it’s OK, stay fat, get diabetes, everybody die. Lose your fingers,” said Joan.

“If you look the way you look, Lena, and that’s fine and you’re funny, don’t say it’s OK that other girls can look like this,” she said, adding, “Try to look better.”
