Watch: Lady Gaga tributes ‘The Sound of Music’ at Oscars...

Is there anything this woman can't sing?
Celebrating the 50th anniversary of the film 'The Sound of Music', Lady Gaga delivered a pitch perfect performance while belting out 'The Sound of Music,' 'Do Re Mi,' 'Edelweiss,' and 'Climb Ev'ry Mountain.' Rocking a flowy custom-made Azzedine Alaia gown, Gaga showed off her impressive vocal range, which came complete with a touch of class... and a well deserved standing ovation.
