Madonna's marriage in trouble?

Madonna and Guy Ritchie are having marital problems, according to media reports.

The superstar singer and her film director husband are said to have had a heated argument after he refused to join her on a recent trip to Malawi.

It is thought that Madonna was upset that Ritchie decided to stay in the UK instead of accompanying her and daughter Lourdes, ten, and 18-month-old David Banda when they went to visit her adopted son's biological father.

Moreover, Ritchie has reportedly been seen dancing intimately with another woman while on a night out with friends at a London club, the Daily Record reports.

Contactmusic quoted the source as telling the newspaper: "Guy went all out to let his hair down. He came with a group of blokes who were all up for having a big night. Guy seemed a bit solemn at first. He seemed determined to drown his sorrows as the drinks flowed.

"Then he hit the dance floor and spotted a leggy brunette. They seemed to just click together. When they got talking they began dancing closely. They didn't leave together but got very close on the dance floor."

Madonna and Ritchie met in 1999 through mutual friends Sting and his wife Trudie Styler, and the couple wed in December 2000.
