It comes after Piers said he is banning Madonna from his new CNN show because she is 'too boring'.
Speaking to Britain's Daily Express last week, Morgan said that the 52-year-old: 'is so boring. She is too vegan for TV. We have Lady Gaga now so Madonna is banned from my show.'
Although the former Daily Mirror editor said he would like to interview Obama, Mel Gibson and Jack Nicholson, when he takes over from CNN legend Larry King in the new year.
In response, Madonna's publicist, Liz Rosenberg, told PopEater.com: 'Madonna doesn't know who Piers Morgan is but she's a big fan of Lady Gaga.'
