Cheryl Cole has gone to Los Angeles amid rumours of a troubled marriage.

The Girls Aloud singer, who has been rocked by claims her soccer star husband Ashley Cole had an affair and was sending explicit text messages to a topless model, was spotted boarding a plane at London’s Heathrow Airport after performing at Brit Awards 2010.

She removed her wedding ring for the show but sported a different, chunky gold jewel, reports the Sun.

Cheryl’s reps have said that the singer will be spending a week in the States “writing and recording sessions”.

A spokesperson for Cheryl added that the trip was scheduled ‘last month’.
