Chaka Khan has thrown bizarre shade in the direction of Ariana Grande, branding the youngster a "heifer" and declaring: "Fuck her!"
The pair have previously worked together on 'Nobody', a song on the soundtrack to 2019's Charlie's Angels, although Khan subsequently described it as "a cute song" which is "not gonna change the world".
Now the veteran musician has ruled out another collaboration with Grande, 27, when questioned about the prospect during an appearance on VladTV.
"Fuck her!" Khan replied. "No, she's all right, she's good on her own.
"I don't want to sing with another woman. I ain't got nothing to say with a woman. You say it by yourself.
"I'm not gonna do a song with no heifer!"
Last year Khan released Hello Happiness, her first new album in 12 years.
