Scottish producer/artist CALVIN HARRIS has delayed plans to work with R+B star Kelis on her latest album because he is "too busy". The Milkshake singer is desperate to work with Harris - who has already collaborated with Kylie Minogue - but the Acceptable In The Eighties star says Kelis will have to wait because of his hectic schedule. He says, "We had a bowl of fruit in a posh London hotel together. I'd love to do stuff for her but it seems like I don't have any time to even take a s**t nowadays. "If I can find some time in the schedule then it's definitely a goer."
