Gwen Stefani's son Kingston takes a tumble off his scooter

They seem to be the must-have toy for every child this summer.

Including Kingston Rossdale, who took his new scooter for a spin around a London park yesterday.

However, the cute four-year-old seemed to be having a bit of trouble getting the hang of it and took a tumble onto the grass.
Kingston was joined by pop singer mother Gwen Stefani, rock star father Gavin Rossdale and little brother Zuma as they enjoyed a family day out at the park.

And while Kingston was busy perfecting his scooter technique, his parents took Zuma on the swings.

He sat on his mother's lap as they swung back and forth together while Gavin checked emails and messages on his phone.
