Word is out that Madonna’s marriage to British filmmaker Guy Ritchie is breaking up.

Sources say the relationship is torn apart by Guy’s jealousy over her success and his misplaced fears that she’s cheating on him. “Madonna’s marriage is definitely on the rocks,” an insider declared. “Guy’s been accusing Madonna of cheating while she’s on tour, and despite her assurances that she’s not, it seems he’s convinced himself that she is.”

“The truth is Madonna isn’t cheating on Guy, and she’s probably fed up with dealing with his insecurities. We’ll just have to wait and see if it all works out. I hope it does though.”
