Joss Stone was told to put a sock in it by Mick Jagger because she refused to sop chatting and singing in the recording studio.
The Rolling Stones legend teamed up with the talkative soul singer, former Eurthymics star Dave Stewart, Damian Marley and composer A. R. Rahman to form a new supergroup.
But as the band, named Superheavy, got together to write their songs in a rehearsal studio Jagger became aware of Stone's annoying habit of singing and talking persistently.
He tells Live magazine: "I know she talks all the time and she is always up and laughing spontaneously. She is not like some broody, moody kind of girl who sits in the corner and you don't know what she's thinking.
"She's telling you what she is thinking all the time, which is quite good really. And she sings all the time. She sings all her thoughts. I say, 'Joss, can I get five minutes off the singing? Joss, shut up. Joss!'"
