Ouch!

Liam Hemsworth was noticeably absent from wife Miley Cyrus' side at the Grammys on Sunday, and now we know it was because he was hospitalized with kidney stones!

"[Liam] was briefly hospitalized. He is at home resting and will be fine," a source dished to People.

The Aussie hunk had to sit out his own premiere for his new flick Isn't It Romantic on Monday, so his bride went in his place!

"So proud of my hunky hubby @liamhemsworth & his newest movie #IsntItRomantic ❤️ He unfortunately wasn’t able to attend due to health reasons… but he is recovering and taking this time to rest / heal," she wrote on social media.

"It’s hard for entertainers to put themselves before the project but this time it was crucial …. I am proud to represent him and his incredible work. So happy to see him shining in this comedy! He is the funniest person I know , and the world now gets to see the Liam I wake up to every day…. luckiest 💋” she added.

He made sure to thank the songstress for her dedication, too.

"Sorry I couldn’t make it to the @isntitromantic premier tonight guys. Been dealing with some pretty annoying health stuff the last couple days. 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!” he responded.

Is there any cuter couple in Hollywood?! We think not!
