"Sorry I couldn’t make it to the @isntitromantic premier tonight guys. Been dealing with some pretty annoying health stuff the last couple days," Liam revealed on Instagram.
Luckily his supportive wife Miley decided to step in and attend the film's premiere for him.
"Lucky I have the best girl in the world to represent for me! Thanks for the support babe! I hope everyone enjoys the movie! It’s a perfect Valentine’s Day flick so if ya ain’t got nothin better to do then go see it! Love to all!
Liam's Isn't It Romantic co-star and fellow Aussie actor Rebel Wilson was the first to share that he had been hospitalised.
“[Liam] was in hospital overnight, so hopefully he will be fine,” Rebel told Extra.
“He texted us this morning."
