Tracee Ellis Ross has the voice of an angel! This shouldn’t be too much of a surprise however, because Diana Ross is her mother. Wednesday (August 12th) the Black-ish star, posted a video on IG of herself singing ‘Lady Sings The Blues.’ Ross is already known on Instagram for being insanely funny but this video was perfection and her fans loved it! The song, ‘Lady Sings The Blues’ was originally sung by Billie Holiday. The song also served as the title for the 1972 film about Holiday in which Diana Ross played the young and talented jazz singer. Check out Tracee’s sweet serenade below.
