Priscilla Lopez is an American singer, dancer, and actress. She is perhaps best known for originating the role of Diana Morales in A Chorus Line. She has had the distinction of appearing in two Broadway landmarks: one of its greatest hits, the highly acclaimed, long-running A Chorus Line, and, as a teenager, in one of its biggest flops, the infamous musical version of Breakfast at Tiffany's, which closed before opening night.
