Keys, Hudson want kids in band
Alicia's three-year-old son Egypt and Jennifer's four-year-old son David Jr could also be joined by Beyonce and Jay Z's daughter Blue Ivy and Pharrell Williams' son Rocket in the pint-sized pop group.
"It should be Jennifer's son David, my son Egypt, maybe even Pharrell's son and Blue. It would be too cute," the Girl On Fire songstress told E! News.
Dreamgirls star Jennifer added: "Rocket and Munch (David Jr)! OMG, they're like in a band. They're in the studio together.
"I think that's a great combination. Blue and Munch still have yet to meet. Munch and Egypt have met. Munch and Rocket are buddies, because I worked with Pharrell in the studio with my album and both Munch and Rocket were there.
"They love each other. T hat's enough because they can't split up their money too far," she added.
