Like most parents of young children, Ryan Reynolds and Blake Lively are sick of listening to the Baby Shark song.
The Hollywood actor has tried to solve the issue in his usual hilarious way - and fans have dubbed it the best parenting advice they've ever been given.
Reynolds took to Twitter to explain that his one-year-old daughter Betty is "obsessed" with Baby Shark.
"All day. Every day. And there's only one way to fix this," Reynolds wrote.
He added a photo of the poster for the 2016 movie "The Shallows" to his tweet. The thriller tells the story of a surfer attacked by a great white shark.
