The 46-year-old singer - who has just released her sixth album 'Detours' - is desperate to duet with "hot" Amy Winehouse, who picked up five Grammy Awards last week while being treated for her drugs addiction.
Speaking at an intimate show in London, she said: "I want to collaborate with Amy because she's really hot and cool right now.
"I know one song 'Rehab' was very popular particularly because a lot of young people are in rehab as well. In fact I'm thinking about going. It looks like loads of fun and I know my career will benefit from it."
