It looks like that it won’t just be Madonna’s daughter Lourdes featuring in her work — four-year-old son David has revealed a love of the superstar’s work, reports.

“He knows every song, every word, every step, and he wants to wear all the costumes,” Madonna, 51, told the British morning show GMTV.

Coming after stage-ready Lourdes, 13, joined her mom in the video for Celebration, performing clearly runs in the family. During her recent Sticky & Sweet world tour, Madonna’s nine-year-old son with director Guy Ritchie, Rocco joined her on stage.

“When he jumped on stage to dance in my last show, I was shocked actually,” she said.

“And secretly, unbeknownst to me, they’re all studying privately with my dancers. And Rocco comes out and busts out like a moonwalk or you know, some kind of break-dancing move.

“He’s always been quite shy so I was shocked when he wanted to be in the show.”
