The star, who has a five-year-old sing, Rocket, with wife Helen Lasichanh, says he has also given up on rapping after his days with N.E.R.D, which he fronted with Chad Hugo and Shay Harley.
He explained: "I didn't like what I was saying. I wasn't comfortable with that. I'm a 40-year-old father now and my life has changed."
