Looks like the Broadway.com Audience Choice Award winner’s the Queen! Idina Menzel nailed her performance of “Let It Go” at the 86th Academy Awards telecast March 2. The Tony winner had admitted that she had to work on the number with her teacher as “it's a challenging song and quite acrobatic, so I have to be in my best voice.” Well, she certainly was, wowing the Hollywood crowd with her rendition of the now Oscar-winning Bobby Lopez and Kristen Anderson-Lopez's-penned song. Definitely worth taking the night off rehearsals for her upcoming Broadway show If/Then! Check out Menzel kill the anthem below!
