madonna learns a few tricks from the circus

Madonna's attempts to keep her performances "edgy" have seen her exposing her breasts at recent concerts. The 53-year-old singer's efforts could become even more daring after she took some tips from the cast members of a vaudeville circus show.

Madonna and 15 members of her entourage, including her 24-year-old boyfriend, Brahim Zaibat, a French breakdancer, attended a performance of Cantina at the Southbank Centre in London this week.

The performance was delayed by 20 minutes to allow the American and her chums to take their seats.

"She spent a lot of time engrossed in conversation with her friends about key bits of the show," says a member of the audience.
