Drew Barrymore shuts down Hugh Grant's singing insult.

Drew Barrymore responded to Hugh Grant's insult about her singing voice in their movie "Music and Lyrics" by posting a video on Instagram singing a duet from the film and dedicating it to him. Grant had called her singing "horrendous" in a recent interview. Barrymore playfully clapped back at him and invited him to join her in singing. Grant has faced backlash over his behavior towards Ashley Graham on the Oscars red carpet.
