Madonna is splitting up with her husband Guy Ritchie, almost eight years after they got married.
The music star married Ritchie, who is a film director, in December 2000 at Skibo Castle in Scotland.
There have been lots of newspaper reports that the couple's marriage has been in trouble, but just last month they were at a film premiere together.
The couple have got millions of pounds between them, and now experts are wondering how that cash will be split.
A statement from Madonna and Ritchie's spokespeople said on Wednesday: "Madonna and Guy Ritchie have agreed to divorce after seven and a half years of marriage, their representatives confirmed today."
Madonna is in the middle of a massive world tour called Sticky and Sweet, which finishes in December. She is due to perform in the American city of Boston later on Wednesday night.
Ritchie is working on his latest film - a version of Sherlock Holmes.
