Madonna has ordered her husband Guy Ritchie to accompany her to London's Brits Awards this week (15FEB06) - in a bid to quash rumours their marriage is on the rocks.

But the 47-year-old pop queen is having to put up a fight, as Ritchie is currently refusing to attend. He also failed to turn up with his wife at the Grammys last week (08FEB06).

An insider tells British newspaper the Daily Mirror, "They are having a real power struggle.

"She wants the whole world to see they are together. But Guy clearly has other ideas.

"Like all relationships, they are going through a bit of a bad patch but he doesn't see why he has to pretend everything is OK just to keep her happy."
