Madonna Banned From Both Of Piers Morgan's Shows

'Welcome to Twitter. You're still banned from my show,' Morgan writes to Madonna.

CNN talk-show host Piers Morgan has not been shy about his feelings about Madonna.

The former "America's Got Talent" judge has been going in on the singer for months, calling her everything from a "con artist" to "gruesome," and making fun of her super-toned physique and Super Bowl halftime show.

But on Monday, Morgan escalated the feud, sending a snippy message to Madonna in which he welcomed her to Twitter while smacking her down once again. The "Girl Gone Wild" singer had set up a special Twitter account on Monday in order to chat with her fans and Morgan wrote, "Welcome to Twitter @MadonnaMDNAday -you're still banned from my show. Love Piers."

That crossed the line for Madonna's manager, Guy Oseary, who responded with his own snap-tastic tweet, posting a letter from October 21, 2011, that says Morgan is "delighted to invite Madonna to be a special guest for his L.A. recording of his U.K. chat show — where she would be welcome to promote her new film and forthcoming album release (and perform two numbers)."

Like a demented game of Hollywood power-broker tennis, Morgan fired the ball back, tweeting, "Madonna's only been banned from my #CNN show @guyoseary - not my UK show, which sent that invite. But I'm now banning her from that too." And he still wasn't done! Morgan then banned Oseary from all his shows too, due to what he called "guilt by association." Morgan has apparently felt slighted over the years by Madonna, especially during his days as an editor at England's Daily Mirror newspaper, where he claims he was lied to by the singer's publicist in order to ensure that a rival paper got Madge's pregnancy announcement.

Morgan caught Madonna on the same day she was finally extinguishing another feud, this one with EDM superstar deadmau5, who had taken the 53-year-old pop icon to task for seemingly making a drug reference during her appearance last weekend at the Ultra Music Festival in Miami.
