R+B superstar Janet Jackson has silenced rumours songs from her hotly anticipated new album have been leaked on the internet - revealing that the tracks are more than two years old. The ALL FOR YOU singer has identified the 'new' material as tracks she recorded with producer RICH HARRISON more than two years ago, and insists she will keep her new material under wraps until CDs hit shops. She says, "A couple of years ago I recorded some tracks with Rich Harrison. But none of that music will appear on my new album. "I have a tight rein on all of the music that has been recorded."
