She grabbed Gwyneth and kissed her full on the mouth

MADONNA grabbed GWYNETH PALTROW and gave her a steamy kiss on the lips at a boozy showbiz party, a sensational new book reveals.

A biography by the Queen of Pop’s brother claims to lift the lid on Madge’s sexual conquests, love affairs, drug-taking and rows with husband GUY RITCHIE.

And it will tell how Madonna, now 49, flirted with Oscar-winning actress Gwyneth at a glamorous New Year party thrown by leading fashion designer DONATELLA VERSACE.

The Like A Virgin singer was dancing on a table at 4am when she dragged Gwyneth up to join her.

Younger brother Christopher Ciconne will tell how he watched as the pair started dancing together.

Then — as party-goers watched in amazement — Madonna grabbed Gwynnie, pulled her to her and kissed the stunned Hollywood star full on the mouth.

Gwyneth — who is happily married to Coldplay singer CHRIS MARTIN — is not the first woman to be snogged by Madge.

She French-kissed BRITNEY SPEARS and CHRISTINA AGUILERA at the MTV Movie awards in 2003.

And Ciccone’s tell-all book — called Life With My Sister Madonna — will tell of lesbian flings and other sordid secrets of Madonna’s past when it is out later this month.

Sources say that Ciccone — an interior designer — will reveal how she took drugs with leading showbiz executives.

Explosive
Ciccone, 47, will also tell all about her rocky marriage to Hollywood actor SEAN PENN.

And the explosive book will spill the beans about her rows with film director hubby Ritchie.

He will say the pair are locked in explosive rows and split by growing differences.

Their seven-year marriage is only kept together by the intervention of a rabbi who travels to their homes to act as informal counsellor.

Homesick Madonna is desperate to return permanently to New York.

But Guy, 39, is said to want to remain in Britain, seeing it as a better home for their three kids.

Ciccone — one of five of Madge’s siblings — has worked closely with Madonna in the past.

However the pair have grown further apart, and now Ciccone has decided to sign a huge deal to tell his story.

A source said: “The book is a warts-and-all account. Chris was there for all the key moments in Madonna’s life. There is no-one better placed to tell the real story behind Madonna’s public image.”

The singer’s spokeswoman said: “Madonna has not co-operated with any biography about herself.”

The book’s publication by Simon & Schuster could not come at a worse time for Madonna, who is fighting off rumours of an affair with American baseball superstar ALEX RODRIGUEZ.

Madonna yesterday ordered Rodriguez — nicknamed A-Rod — to keep silent about their relationship.

She also asked him to tell his family to “shut up” after a series of leaks revealing his wife Cynthia had fled to Paris.

A source said: “Madonna has contacted A-Rod and asked him to stay silent. She has issued a statement that they are just friends and, as far as she’s concerned, that should be it.

“Madonna is furious that other people have revealed that A-Rod’s marriage is on the rocks.

“She wants to stop the leaks and the whole thing to blow over. She told him his family must shut up.

“All of this speculation is taking its toll on her. She wants to concentrate on rehearsing for her tour and spending time with Guy.”

Rodriguez, 32, was last night said to be pleading with Cynthia to return to the US for crunch talks.

She jetted to Paris to stay with rocker pal LENNY KRAVITZ in a bid to escape the firestorm surrounding her marriage.

But sources say she is digging her heels in. One said: “She’s not ready to rush back. She feels she’s been treated pretty poorly by him.

“He wasn’t there for her following the birth of their second baby, he has been cold and distant.

“She is bemused by his sudden interest in Kabbalah.”
