The `Promise This` singer flew to Camp Bastion in Helmand Province in the south west area of the country last night (13.09.11) to film a special tribute to mark 10 years of UK forces fighting in the war torn region and said she was "delighted" to be there.
A friend of the pop star added: "Cheryl`s amazed by the courage of all those serving our country.
"When she was invited to go out to see them in Afghanistan, she immediately said `yes`.
"She thinks it`s such a great cause ad they deserve all of the recognition they get."
Cheryl, 28, flew to Afghanistan on a troop carrier from RAF Brize Norton in Oxfordshire with soldiers from 20 Brigade who are about to start a six-month tour of duty and raised their spirits during the 12-hour flight.
One soldier told the Daily Mirror newspaper: "I couldn`t believe it was Cheryl joining us.
"It`s great she`s made the effort to come all the way out here. Not only does she look amazing but it`s a pretty big gesture, it`s cheered everyone up."
Cheryl underwent hostile environment training before the secrettrip and is expected to meet with troops, travel in a heavily-armed Jackal vehicle and attend a performance by the Royal Marine band.
The dog lover will also meet military dogs responsible for sniffing out bombs and members of the counter-Improvised Explosive Device team who are responsible for device disposal.
