Drew Barrymore Responds to Hugh Grant Calling Her 'Horrendous' Singer: 'Dogs Bark Better'

On Thursday, "The Drew Barrymore Show" host took to her Instagram page (and her show's page) complete with a hairbrush mic to serenade her "Music and Lyrics" co-star.

After belting out a few lines from the film's "Way Back Into Love," Barrymore looked into the camera with a smile and said, "Oh Hugh ... bert, Hubert, that's for you!"

Hugh Grant is singing like a canary.

During a Wired Autocomplete Interview, Grant was asked if he actually was singing in his 2007 rom-com "Music and Lyrics."

Speaking with his "Dungeons & Dragons: Honor Among Thieves" castmates Chris Pine and Michelle Rodriguez (all of the actors took turns answering "the web's most-searched questions"), the British star gave a characteristically candid response.

"Does Hugh Grant actually sing in 'Music and Lyrics?'" Pine read aloud from the poster board.

"Yes, well I do, but I'm auto-tuned beyond belief," Grant said in reply ... and could have stopped there but didn't.

"Actually, that's not true, I'm auto-tuned a bit, but not as much as some," he added before dropping his costar into the conversation. "Drew Barrymore was 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," Grant said without prompting.

Rodriguez was the first to respond, simply saying "Oh snap!" while Pine broke into laughter.

"But having said that," Grant continued, "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'm meant to be rock 'n' roll."

Meanwhile, Grant went viral for something else this week due to an awkward interaction with Ashley Graham on the Oscars red carpet -- see that in the link above!
