Gwen and Gavin caused concerns for minders

Gwen Stefani caused concerns for her minders yesterday when she Gavin and Kingston were late returning from a morning stroll through Brisbane's CBD.

The trio headed off just after 7am and returned some hours later, a good half hour after the 80-strong entourage had checked out of the Sofitel and headed to the airport to catch a 1pm flight to Sydney.

"We're a little late," Gwen said on their return. "We got a little lost. It was great, though."

Gwen and Gavin's trek through Brisbane included the Riverside Craft Markets at Eagle St, where the two enjoyed buying some playpen goodies for their son.

"We bought some toys for Kingston," Gavin said.
