Out of all the coaches, I produce and write songs for other people and the last thing you want to do is be in the studio flirting with Gaga or flirting with Britney,’ he said. ‘You’re not going to get work done [if you are] flirting with Fergie. Or flirting with f***ing Usher. You are never going to get work done.
