Mic drop!

Drew Barrymore is responding to Hugh Grant's critique of her voice through song.

The Dungeons & Dragons: Honor Among Thieves actor was recently asked whether he actually sang in their 2007 rom-com Music & Lyrics. And amid singing the praises of auto-tune, he took a moment to comment on his co-star's musical skills.

"Yes well I do, but I'm auto-tuned beyond belief," Grant stated while answering internet searches in a video for WIRED's Autocomplete Interview March 13. "Actually that's not true. I'm auto-tuned a bit but not as much as some. Drew Barrymore is in that film with me, and I don't think she'd mind me saying her singing is just horrendous. I've heard dogs bark better than she sings."

He added, "But having said that, once they tuned her up, she sounded way better than me because she's got heart and voice and Rock 'n' Roll whereas I sounded like Julie Andrews and I meant to be kind of Rock 'n' Roll as well."

Well, it appears the Notting Hill star's comments got back to Barrymore because she posted a video of herself singing "Way Back into Love," the single their characters write together in Music and Lyrics. And after performing the a cappella rendition into her hairbrush microphone, the actress shared a message for her former co-star.

"Oh, Hugh-bert, Hubert, that's for you," she noted, captioning the March 16 Instagram video, "#SingForHughGrant JOIN ME."

But don't let this back-and-forth fool you into thinking they don't have a harmonious friendship. On the contrary, Barrymore and Grant have fond memories from their time working together.

"I loved getting to know you on our movie Music and Lyrics, and it's just one of my very favorite movies," she said when he was a guest on a 2021 episode of The Drew Barrymore Show. "And it makes me so happy. It was a good movie, it was a happy movie."

Grant agreed. "I love to hate the films I've been in, and I do hate some of them," he shared. "But Music and Lyrics, it's impossible to hate. We're so good in it and so charming."

In fact, he said the two "had a bit of chemistry." But Barrymore explained it didn't form right away.

"It was funny too because when Hugh and I met, Hugh, you can be a bit of a curmudgeon from time to time," she noted. "And I, of course, am like a Labrador in heat…and so excited with joy. So when we both met, we were like, 'Oh, we're kind of different people.'…And then we really got to know each other and accept each other for who we were and it became easy. And we used to sit around and laugh."
