After sometimes, new rumors on Madonna's marriage break up are heating up again. It is said that the diva's marriage to director husband Guy Ritchie is on the rocks due to her plan to expand the family with another adoption.

The couple, who has been married for seven years, has allegedly been fighting since Madonna's latest visit to Malawi. Ritchie reportedly is not keen to expand his family because of the uproar over their adoption of one-year-old Malawi boy David Banda last year.

"They're in total meltdown and row non-stop whenever they see each other," News of the World quoted a source as saying. "They're even spending more and more nights in separate bedrooms. They're a united front when their children are involved. But behind closed doors they barely speak."

The source, moreover, said that Ritchie is sick of being known as 'Madonna's husband', and is worried her fame is overshadowing his own profile as a movie director. Now that everything is getting worse between the pair, let's see if they can make it through.
