britney spears with son jaydenWhile mum Gwen Stefani and dad Gavin Rossdale are busy with new son Zuma Nesta Rock Rossdale, their older son Kingston Rossdale enjoyed a play date with Britney Spears and her sons Sean and Jayden.

Kingston, along with his nanny, were spotted at Britney Spears‘ Studio City home during one of her thrice-weekly visits with her boys Sean and Jayden, who turn 3 and 2 next month respectively. Kingston, who turned 2 in May, was spotted riding around in the boys’ electric car while Britney (pictured holding Jayden) and Kingston’s nanny looked on.

An onlooker reported: “Britney looked really happy and relaxed playing with all three boys.

“A year ago, Gwen and Gavin wouldn’t have dreamt of letting Britney near their son even with a nanny present so Britney must see it as another positive sign that people think she’s getting better again.”

Gwen and Gavin took their new son Zuma, who was born on Thursday afternoon, home from the hospital this weekend.
