Madonna's Polish birthday

Madonna celebrated her birthday with her Polish fans.

The '4 Minutes' singer was performing in Warsaw on Saturday night (15.08.09) when the huge audience launched into a rendition of traditional Polish birthday song 'Sto Lat' ahead of her turning 51 on Sunday (16.08.09).

Lyrics include: "Good luck, good cheer, may you live a hundred years."

The overwhelmed pop star told the crowd: "I feel your love!"

During the show - part of her 'Sweet and Sticky' world tour - Madonna also paid an emotional tribute to the late 'King of Pop' Michael Jackson, who died in June aged 50.

A dancer impersonating the 'Bad' singer performed his iconic moonwalk dance move on stage while wearing a sequined jacket, white glove, white socks and a white T-shirt.

A large photograph of the legendary singer as a youngster was also displayed.

Madonna shouted to fans: "Let's give it up for one of the greatest artists the world has ever known."
