Miley Cyrus stepped up for Liam Hemsworth tonight, representing her new husband at his Isn't It Romantic premiere since he was sick. (Hemsworth skipped the Sunday press day for the film because he was in the hospital.) The singer wore the most exquisite-and Valentine's Day-esque-red ruffle Valentino gown on the red carpet:

And she gave Variety an update on Hemsworth: He is focusing on his health. "He’s down," she said. "He’s not feeling well right now. He just had some health things, and I think that’s the most important-that entertainers, we have a really hard time taking care of ourselves because this movie is the most important thing to him so I had to be here to represent it," she said.

"And I’ve heard he’s just so funny in it, which I’ve always known," she continued. "He’s the funniest person I’ve ever met, but not everyone else knows that so I think this is going to be an amazing step for him." When Variety's reporter said she was a good wife, being there despite her absence, Cyrus had a playful retort. "I already had the dress. Everyone thinks I’m here for Liam but I’m really here for Maison Valentino, yeah."

On Instagram, Hemsworth gave his own update, thanking Cyrus for her support. "Sorry I couldn’t make it to the @isntitromantic premier tonight guys," he wrote. "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!

On both her Instagram and Twitter, Cyrus explained how proud she was of Hemsworth. "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.

He is the funniest person I know , and the world now gets to see the Liam I wake up to every day.... luckiest 💋"
