Country star Carrie Underwood is performing through the pain after injuring herself in rehearsals just days before her live TV production of The Sound Of Music. The singer takes on the role of Maria, made famous by Dame Julie Andrews in the 1965 film, in the ambitious project which will be aired live in the U.S. on 5 December (13). Clumsy Underwood has now revealed she accidentally hit herself in the face with a guitar on Monday (02Dec13), and fell over during a leapfrog scene, which has now been removed from the show to avoid a repeat of the accident. In a series of posts on Twitter.com on Tuesday (03Dec13), she writes, "So yesterday I hit myself in the head with my own guitar & later fell on my face playing leap frog! What do today's rehearsals have for us?... PS - I no longer leap frog (sic) in the show..." The show also features True Blood star Stephen Moyer and Tony Award winner Audra McDonald.
