After a night of trick or treating Gwen Stefani took her boys to the park in Los Angeles on Sunday (November 1) to run off some energy from all the candy they collected.

While Kingston hung out with the nannies, Gwen and Zuma could be seen redefining cuteness as they enjoyed some time on the slide.

Meanwhile, family patriarch Gavin Rossdale has revealed that he wants to perform a duet with 3-year-old Kingston.

He tells Popeater: “At the last benefit we were at, he wanted to get on stage with me and sing. I told him we can, but we have to practise a bit first.”

The 42-year-old rocker continues: “He always wants to come now. During the show, he loves to be on stage on the side. But he loves to play the drums during the sound checks and play with my guitar pedals. He likes to check the mic.”

Kingston and 14-month-old brother Zuma regularly go on tour with both Gavin and Gwen’s band No Doubt.
