British singer Cheryl Cole has flown to Afghanistan to visit U.K. troops serving in the war-torn country. The Girls Aloud star made her way to the country's Helmand Province on Tuesday night (13Sep11) to surprise servicemen and women. Cole underwent special training to prepare for the hostile environment she will tour during her visit, which marks 10 years of British operations in the country. Her morale-boosting trip is being filmed as part of the annual Pride of Britain Awards, which will air on U.K. TV next month (Oct11). A source tells Britain's Daily Mirror, "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 and they deserve all the recognition they get." Cole has largely been out of the public eye since she was fired from the U.S. version of The X Factor earlier this year (11).
