British newsman Piers Morgan has finally revealed the real reason for his long-running feud with Madonna - he once hurled a bread roll at her during a celebrity dinner party. The CNN anchor and former U.K. tabloid editor has made no secret of his hatred for the Material Girl over the years, and even banned her from both his U.S. and U.K. shows in 2011. He has previously remained tip-lipped about what caused the bad blood between the pair, but he has now revealed the bizarre reason behind the falling out. Morgan explains that in 2001, he attended celebrity chef Marco Pierre White's 40th birthday party, where Madonna and her then-husband Guy Ritchie were also guests. Morgan claims the singer was irritated by the dinner's entertainment, late comic Bernard Manning, so he decided to throw a bread roll at the Queen of Pop. He tells Britain's OK! magazine, "Madonna is pretty awful. She never forgave me for throwing a bread roll at her at Marco Pierre White's birthday. She was just being really obnoxious, not just to me, but generally. There was only 40 of us at this dinner party and she got annoyed because Bernard Manning started being offensive and that wound her up. She was with Guy Ritchie at the time and he'd been laughing his head off... I just picked up a bread roll and chucked it at her! "I hate the phoney accent, the muscled arms, the stripping off in her mid-fifties... Everything about her is attention-seeking - I think her 15 minutes of superstardom has probably run its course."
