Superstar Madonna's publicist is hitting back at reports that the pop superstar’s marriage to husband Guy Richie is in trouble, insisting the couple is "joyfully" back together after separate promotional commitments kept them apart.The marriage came under intense media scrutiny last week when Ritchie failed to show up at New York’s Rock & Roll Hall Of Fame induction ceremony, where his wife was honored.This was the latest of several events the couple had failed to attend together, prompting scurrilous reports they’d split. But Madonna’s longtime publicist Liz Rosenberg has attempted to end the rumors and speculation by issuing a press statement. She says, "I am delighted to confirm that Mr. and Mrs. Guy Ritchie remain happily married."Though they were in different countries recently, Madonna in the U.S. doing promotion for 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."
