Sir Cliff Richard has revealed that he would work with Lady GaGa if she toned down her outfits.
The 70-year-old singer insisted that he is open to the idea of duetting with different artists.
He told Bang Showbiz: "I wouldn't mind singing with Lady GaGa but she can't wear any of those hats."
Richard also said that singers Leona Lewis and Adele have "fantastic" voices but admitted that he was unsure if their success would last.
