The camera loves her daughters Lourdes, 16, and 7-year-old Mercy James. Son David, also 7, won hearts by opening mom's recent MDNA Tour with a DJ set alongside Martin Solveig.
But Rocco Ritchie, Madge's 12 year-old with film director Guy Ritchie, may prove the biggest potential showbiz legacy currently living under her roof.
"He's disconcertingly comfortably on stage," Madonna revealed on Tuesday in New York, at a premiere screening of "Madonna: The MDNA Tour," an Epix documentary about her high-grossing trek around the world in 2012.

If you catch the documentary, however, don't expect to see the same cherubic blond boy wherever Rocco turns up next. His mom says he's changed a bit.
"In one year, he's grown. He's six feet tall, his voice has deepened and I'm a little bit scared of him," she noted. (Check out the difference a year makes in the photos above!)
An afterparty followed the screening at nightspot Harlow, where guests like John Travolta, Kelly Osbourne, Zachary Quinto, Martha Stewart, Questlove, and J. Crew's Jenna Lyons danced until last call.
While DeLeon tequila cocktails flowed, Madonna stuck close to her dates for the evening — boyfriend Brahim Zaibat and kids Lourdes and Rocco.
He may be the most eager in Madonna's brood, but even stars need supervision.
