She will spend three nights performing at the Forum in Los Angeles before moving on to Las Vegas.

The 50-date Re-Invention Tour will also travel to Canada, the UK and Paris, ending in September.

During the tour, Madonna will be involved in making a documentary chronicling behind-the scenes action for a later cinema release.

More than 750,000 fans are expected to see the show as it makes its way across North America and Europe, where she will showcase music from her 20-year career.

Madonna had signalled her intention to perform in Israel but has now called off these dates.

She has said she wanted to concentrate on the European dates, but The Sun newspaper reported they were cancelled due to safety fears.

Madonna's entourage includes more than 100 personnel including technicians and stage hands. There will be 12 dancers and five musicians accompanying her.

Scottish bagpipe player Calum "Spud" Fraser will also be a regular performer after he played at the christening of the singer's son Rocco in 2000.

Among the designers brought in to create costumes for Madonna are Karl Lagerfield, Stella McCartney, Jean Paul Gaultier and Prada.

This will be Madonna's first live dates since 2001, when she embarked on the Drowned World tour.
