The 22-year-old singer revealed that she felt baffled on the set of the Channel 4 chatshow - because she was asked to take part in a pie-making contest after being interviewed.
Speaking to Celebs On Sunday magazine, she explained: "I felt so out of place. I thought I was going to be singing - instead I got asked to take part in a pie-making competition, and I'm not the pie-making type.
"Kim Cattrall was there too and she made such a good pie - and mine was crap."
She added: "Mel B and Mel C were there too and they were amazing. Mel B and I have been mistaken for each other so we bonded over that."
Knowles was forced to deny claims that she had been axed by her record label earlier this year.
