Madonna's daughter will be among the backing dancers for the singer's world tour.

Lourdes Leon - the 'Hung Up' hitmaker's 15-year-old child with former boyfriend Carlos Leon - will take to the stage alongside her mother for the first time when Madonna's 50-country run of shows begins in Israel in May.

A source told the Mail on Sunday newspaper: ''It is the first time Lourdes will have appeared on stage with her mum.

''There are risqué dancers and some blatantly sexual dance routines - but Madonna is really excited about Lourdes making an appearance.''

Madonna was joined by Lourdes and her dancer boyfriend Brahim Zaibat when she recently chose a new backing dancer for her tour.

The 53-year-old singer was at the Smirnoff Nightlife Exchange project in New York in November when she selected Lil' Buck to join her on tour and the performer - whose real name is Charles Riley - and he said the experience was a dream come true.

Lil' Buck explained: ''This has been an incredible Journey and a dream come true.''

Lourdes previously appeared in a video for Madonna's 2009 single 'Celebration'.
