Madonna has vehemently denied reports her marriage to Guy Ritchie is on the rocks.The 49-year-old pop star's representative issued a statement insisting the couple, who have been married for seven years, couldn't be happier following various reports they live separate lives and are on the verge of splitting.Liz Rosenberg, Madonna's US spokeswoman, said: "I am delighted to confirm that Mr. and Mrs. Guy Ritchie remain happily married."Though they were in different countries recently - Madonna in the US promoting her upcoming album 'Hard Candy' and Guy finishing up post-production on his new film 'RocknRolla' as well as completing a Nike commercial and working on several scripts in England - the family are joyfully back together at home in London. All is well and wonderful in the Ritchie household."Rumours suggesting the couple's union is in trouble have been rife for several months. They have not been pictured together since January 8, when on a trip to India.Speculation intensified when Guy, 39, was noticeably absent from Madonna's induction into the Rock and Roll Hall of Fame in New York.According to reports, the couple - who have a seven-year-old son Rocco, an adopted son David, two, and an 11-year-old daughter Lourdes from Madonna's previous relationship - have been living like "brother and sister" rather than husband and wife and have even divided their London home into two separate living quarters.

A source said: "The marriage is hanging by a thread.

"No one doubts they adore their three kids - but the children seem to be the only reason they are living this strange loveless existence."

It was also suggested Madonna was intending to move back to the US with the children, while Guy would remain in the UK.
