Piers Morgan I Want Madonna to Apologize To Me ... ON BENDED KNEE 
  
 wantsto "get down on bended knee" and apologize to him ... on TMZ -- all because of a mystery feud that blew up on the Internet this week.You'll recall ... Piers publicly banned Madonna from his CNN show on Twitter Tuesday, writing, "Welcome to Twitter. You're still banned from my show. Love Piers X."Madonna's manager Guy Oseary thumbed his nose in response, tweeting back Madonna had already been invited to Piers' UK show -- so Piers extended the ban worldwide.Piers refused to elaborate on what's really behind the feud -- on his way out of an L.A. supermarket today -- telling us, "It's a private spat." (Piers also doesn't return his shopping cart to the cart corral in the parking lot ... but that's another issue.)Piers added, "Madonna can come on [my] show, but she has to get on bended knee and apologize to me ... on TMZ."But he probably won't get his wish -- because a source close to Madonna's management tells TMZ, "Piers is delusional for feuding with Madonna. He isn't even on Madonna's radar. The UK invitation speaks for itself." ||||| A day after house music producer Joel Zimmerman (stage moniker: Deadmau5) slammed Madonna's reference to ecstasy as irresponsible, the popstar tweeted an attempt at reconciliation at him. 
  
 Madonna was hosting a Twitter question and answer session to promote her album MDNA which was released Monday. Soon enough, a comment from Zimmerman's Twitter account appeared: 
  
 @MadonnaMDNAday You're a role model to 100's of millions. You have a powerful voice,EDM could use your positive influence, not "molly" talk. — deadmau5 (@deadmau5) March 27, 2012 
  
 Zimmerman was referring to an incident that took place at the Ultra Music Festival in Miami. When Madonna took to the stage Saturday night to introduce Avicii, she asked, "How many people in this crowd have seen molly?" 
  
 Molly is a slang term for MDMA, the active chemical in ecstasy, a drug often associated with electronic dance music (EDM) concerts. The crowd erupted in cheers after Madge asked the question. When Zimmerman caught wind of the incident, he went on a multi-Tweet and Facebook status rant that blasted Madonna as, among other things, "a f-----g idiot" who was trying to stay relevant by trading on a negative and dangerous association. 
  
 He gathered his thoughts into a somewhat tamer blog post, in which he explained that he was offended by Madonna's recklessness (given that there were young fans in the crowd and the concert was being live-streamed on YouTube). 
  
 This time, though, Madge was prepared for his opinion. She quickly responded with a photo message: 
  
 The text of the photo reads: "From one mouse to another. I don't support drug use and I never have. I was referring to the song called 'Have You Seen Molly' written by my friend Cedric Gervais who I almost worked with on my last album ..." 
  
 The song she's referring to is a house music track. In a teaser video for the Gervais song, a computerized female voice says that "Molly" helps her dance and asks for help finding "Molly" at a chaotic rave. Though it's perhaps speculative, it would certainly not be surprising if the Gervais song is also about ecstasy. 
  
 Deadmau5 appeared somewhat satisfied with Madonna's explanation, tweeting, "fair enough, i was just voicing my concerns as i usually do. +1 respect for clearing it up personally." The two exchanged a few more tweets and Zimmerman sent a message to his own followers: "well there you have it kids. i've said what i needed to say, which ill still stand by, and so did she. life goes on. no more talk of that." 
  
 What do you make of Madonna's explanation? Is it possible that Madge didn't think the 150,000 or so people watching the concert wouldn't have thought she was referring to the drug? Let us know in the comments.

The latest to slam Madonna: electronic musician Paul van Dyk, who calls her "so stupid" in Billboard. "She made the biggest mistake of her career" when she apparently referenced drugs "in front of a crowd of 18-year-olds" at the Ultra Music Festival on Saturday, he says. Madonna, introducing festival headliner AVICII, asked, "How many people in this crowd have seen Molly?" Molly is a street name for MDMA, the active substance in ecstasy. Madonna was called out for the question by Deadmau5 earlier in the week, and she tweeted an explanation (complete with a picture of her in mouse ears) in response, but apparently van Dyk was not convinced: She says she was referring to "Have You Seen Molly," a song by her friend that is totally not about drugs. That friend, Cedric Gervais, also insisted the song really is about a girl named Molly who just so happens to make him, you know, "want to dance." But TMZ doesn't seem convinced either, likening the song to Britney's "If U Seek Amy." Poor Madonna—who's been in the news quite a bit thanks to the release of her latest album MDNA—just can't catch a break this week: Piers Morgan welcomed Madonna to Twitter Tuesday by informing her, "You're still banned from my show." He later extended the ban to both his US and his UK show, but so far he hasn't explained his beef with Madge. He did, however, tell TMZ yesterday that he wants her to apologize for the mystery slight "on bended knee." YouTube declared Madonna's latest video, "Girl Gone Wild," too racy for younger viewers and put an age restriction on it, E! reports. And ABC isn't happy with her also-racy ad for new fragrance Truth or Dare, asking her to clean it up before it can air. And as if all that was not enough, her 15-year-old daughter was caught smoking.
