@ONYX...Janet did have some words for Madonna back in the day:

There was an interview with MTV where she said that she felt that her music style had more class than Madonna's and in the Vibe magazine where she has the You Want This outfit on the cover, she was asked about Madonna and her response was that her mother told her if she didn't have anything nice to say, then don't say anything at all.

But all of that was around the time Madonna was being a B***H to Michael and we all know Janet don't play when it comes to takin pot shots at him.
