Classical singer Katherine Jenkins has signed up to tackle a half-marathon for charity.

The Welsh beauty is gearing up to run the Royal Parks Foundation Half Marathon through London on 7 October (12) to raise money for the Grief Encounter Project, which helps kids cope with the loss of a parent.

The former Dancing With The Stars competitor has had just three weeks of training, and admits she is nervous about the gruelling race.

In a post on her fundraising website, she writes, "Please please please... dig deep, donate and pray for us! We're gonna need it!"
