Washington, July 10 : It seems that Madonna's brother Christopher Ciccone is stretching the truth quite a bit when he writes in his upcoming memoir that Madge and Oscar winner Gwyneth Paltrow locked lips for a steamy kiss at a party.
In 'Life With My Sister Madonna', Ciccone claims that the incident happened during a New Year's party thrown by Donatella Versace.
However, a guest who was at the do has now rubbished the claims, insisting there was no same-sex kissing between the two women, reports E! Online.
"I was at that party and did not see anything at all like what was described," said the partygoer.
Madonna and Paltrow have refused to comment on the claims.
Another claim that's going unanswered is the one that Ciccone makes about his sister's ex-boyfriend Warren Beatty.
In the tome, Christopher says that Beatty once cornered him and grilled him on what it's like to be gay.
While Beatty remains mum, Madge's rep Liz Rosenberg, would only say: "There is no subject that doesn't fascinate Warren Beatty."
The book hits stands on July 15.
