London, Mar 02 (ANI): Popstar Gary Barlow may not be able to make it to the top of mount Kilimanajro, as he is suffering from acute backache.
The 'Everything I Ever Wanted' hitmaker has been walking with the help of two poles under the observation of two doctors.
Due to the injury caused by his tough training, Gary has been climbing the mountain on a slower pace, thus other participants including Cheryl Cole are also left behind.
However, the grueling training seems to have taken a toll on the pop star, as his doctors fear that he may undergo more pain while trekking.
"The medics on the ground say his back should loosen up the more he walks but the fear is that he may trip over and really put his back out," the Daily Star quoted a source, as saying.
"If that happens halfway up the mountain then we have serious problems," the source added.
Meanwhile, Cheryl revealed that the grueling training has taken a toll on her too, as she got blisters on her feet due to the training.
"I've got blisters on every toe of both feet. I sent my friend a text message the other night after a 12-mile walk on the treadmill," Cheryl said.
"When I went to bed I honestly thought I wouldn't be able to get up in the morning," Cheryl added. (ANI)
