There’s a show-stealing performer clogging Madonna’s Instagram feed—and it’s not who you think! Madonna’s 10-year-old daughter Mercy James stole the spotlight this morning when her Material Girl mom posted a video of her belting out Roth B’s “Lost Boy” alongside Debi Mazar’s daughter, Giulia.

The proud mother of four showed her support with this enthusiastic caption: “Competition! . Mercy James and Giulia EXPRESS THEMSELVES! @debimazar”

Mercy appears to be enjoying herself as she and Giulia (clad in matching life jackets) get into the groove on an evening boat ride. The 10-year-old takes a cue from her mother, the queen of pop, and adds some serious pizzazz to her performance, including creative choreography and dramatic facial expressions.

We see great things on the horizon for Madonna’s protégé daughter. Looks like Mercy might just grow up to be a triple-threat, like her famous mom!
