Katy Perry frolics in the sea off Hawaii

LA: The US-born pop star was snapped enjoying a refreshing dip in the Pacific Ocean without her wedding ring.

Meanwhile Brit funnyman Russell, 36, was spending the festivities with friends in a rented cottage on the Cornwall coast.

According to the Sun.co.uk, Curvy Katy, 27, seemed in a world of her own as she played in the surf with a group of pals — including a long-haired lookalike for Russell, who she wed a year ago.

Wearing a grey bikini, she looked relaxed as she laughed and swam.

An onlooker said: "She looked great and seemed like she didn't have a care in the world."

Katy and Russell have been forced to deny a string of claims that their marriage is on the rocks.

Just weeks ago Russell told US chat host Ellen DeGeneres: "I am really happily married."
