Joan Rivers faced backlash by the TV audience at The David Letterman Show after she joked about Adele and her weight.
The 79-year-old TV comedian suggested that the British singer should change the name of one of her hit songs to Rolling In The Deep Fried Chicken.
This comment was received with boos from the audience and a bit of laughing, the Mirror reported.
Rivers then said that Adele was very scared because she sang at the awards.
She said, "My throat, my throat! I don't know if I can swallow. And I said, Oh yeah, you can swallow," she added.
This is not the first time that Rivers has made a joke at Adele's expense.
On Oscars night, she had tweeted that on Sunday night, people could easily pick Adele's Oscar statuette out of a lineup as it was the only one that was wearing Spanx.
And when Adele gave birth to her son, Angelo James, in October, Rivers tweeted, "Congratulations to Adele on the birth of her 68 pound 8 ounces bouncing baby boy."
