Madonna's teenage daughter Lourdes will reportedly join the pop superstar on her upcoming world tour as a backing dancer.
 
The singer is preparing to hit the road later this year for a series of shows across the world, and 15-year-old Lourdes will appear with the star's team of backing dancers for a number of the concerts, according to Britain's Mail on Sunday.
 
A source tells the publication, "Madonna is really excited about Lourdes making an appearance."
 
Lourdes previously joined her mother on stage during a gig in Israel in 2009 which marked the final show of her Sticky & Sweet tour, and the youngster also danced in the video for Madonna's Celebration track.
 
The new tour kicks off in Israel in May.
