Drew Barrymore
When director Woody Allen dubbed her vocals in the 1996 musical Everybody Says I Love You, a mortified Drew Barrymore vowed never again to be humiliated for her poor singing. So she enrolled in some voice training and singing class, and voila! a decade later and Drew had singing credits to her name!
In 2007's Lucky You she performed two songs that appear on the film's soundtrack, including the well-received single The Cold Hard Truth.
