The Believe hitmaker was taking part in a question and answer session with fans on Reddit.com on Saturday when she was asked if she still hates Madonna, a year after appearing to criticise the Material Girl's decision to call her last album MDNA, a take on party drug MDMA.
She replied to the fan, 'Madonna, no. Actually I don't (hate her). I never hated her, I just thought she was a b**ch. Actually I quite respect her.'
She went on to lavish praise on the blonde singer, adding: 'Actually I think Madonna might be one of the most amazing artists I've known. I don't like everything she does, for sure, but she is always riding the crest of the wave. She always saw trends way before anyone else, and had great videos.'
Cher came under attack from Madonna's loyal following last year after sarcastically branding her MDNA album title 'tasteful'.
The 67 year old also previously took aim at the pop veteran during Madonna's 2006 Confessions tour, when Cher insisted stunts like entering from the ceiling and cracking a whip were eerily familiar to her own past stage antics.
She said, 'I look at Madonna and think, 'Nice try dear, but you're not doing anything I didn't do 20 years ago.''
