Janet Jackson topless in Vibe

Jumping Jackson!

Janet Jackson (can you beleive this girl is 40) has been going topless once again. This time, it's not in front of millions in the Superbowl, but on the front cover of Vibe magazine. She was asked by the mag if she would ever stop getting her kit off, to which she replied; "Of course. When I'm 80 - that's when I'll call it quits." The singer is about to launch a new album, entitled 20 Y.O, which is out later in the year. She is rumoured to be about to marry boyfriend and music producer Jermaine Dupri. Vibe is on sale now.
