Jay Z has already signed a slew of big names to his Roc Nation label including Rihanna and Willow Smith. Now, Hov is expanding into more Hollywood royalty by signing the kids of director Steven Spielberg.

The YBF shares that Sasha and Theo Spielberg a.k.a. singing duo Wardell are part of Jay's musical family now.

The kiddos are Spielberg and wife Kate Capshaw's offspring. Theo was adopted by Kate before her marriage and later, adopted by Steven too.

Wardell released their 'Brother/Sister' EP recently. They describe their music to Teen Vogue as beachy and California. "The beach and the ocean are such a constant part of Los Angeles life, so that definitely seeps into our music. Classical music as well—they really knew what they were doing back then. Being moody is also a good path to a nice song," says Sasha.
