New Delhi, July 16 : Madonna went under the knife in a bid to maintain her youthful appearance, says her brother Christopher Ciccone.
Christopher, who has written a book entitled 'Life With My Sister Madonna', alleges that the singer, who turns 50 in August, had a facelift.
When asked if he still recognised Madonna from the girl he grew up with, Christopher replied: "Not after the facelift."
"I do recognise her in some ways, but I think ultimately she is a lonely person. It is truly lonely at the top," China Daily quoted him, as telling US TV show 'Good Morning America'.
Christopher recalled the moment his relationship with Madonna started to deteriorate, during the filming of her 1991 documentary 'Truth Or Dare'.
He said: "When she was rolling around on my mother's grave in 'Truth or Dare' that was a turning point for me. I kept it inside but I thought, 'OK, there are no boundaries here. My mother has now become a bit player in her life story', that hurt me, my relationship with her changed."
Christopher says despite his revelations about the singer, he is hopeful they will mend their relationship in the future, so he can get to know his extended family.
