Madonna has furiously denied reports her close relationship with producer Stuart Price is threatening her marriage to Guy Ritchie.
The Daily Mirror, has claimed the Hung Up singer spends all her available time with the 28-year-old musician - despite work on their project album Confessions On A Dancefloor having long finished.
A source tells the tabloid: "It's no secret that Madonna and Stuart have developed a special working relationship. They enjoy each other's company and respect each other. She confides in him and regards him as one of the most important people in her life."
But the 47-year-old singer's publicist Liz Rosenberg insists Madonna has only sisterly feelings towards her young colleague.
She says: "There's no strain in Madonna's marriage. Her relationship with Guy is good. They are happy. She treats him (Price) like a little brother. They have fun and talk a lot."
