Rebel Wilson and Liam Hemsworth are co-starring in the new rom-com, "Isn't It Romantic."
In the film, Wilson's character hits her head and wakes up to discover that she's playing the leading lady in a romantic comedy with Hemsworth as her love interest.
"I don't think I could've got anyone better," Wilson said of her co-star. "Liam, not only is he just such a lovely guy, he's so funny in the film and he sings and dances in the film too."
Hemsworth recently wed longtime love Miley Cyrus in an intimate affair.
"It was a really special day," Hemsworth told "GMA."
Although it's Hemsworth and Cyrus' first Valentine's Day as a married couple, Hemsworth confirmed that Cyrus extended the invite for Wilson to crash their date.
"I think she should've asked Liam before," Wilson said, laughing. "If I get desperate, great option."
Hemworth chimed in, "I'm all for it. Absolutely."
Wilson, who is single, said she's been picking up dating tips from books on tape. She even shared some valuable advice with "GMA" viewers who may be looking for love.
"Because I'm quite a strong, independent woman, it's good sometimes to give the guy something to do," Wilson said. "I might say, 'Would you mind holding my jacket?' And then you'll say, 'Sure' because you're an awesome guy."
She went on, "You doing me a small favor weirdly makes you closer to me, psychologically. So girls, get the guy to hold your handbag, hold your jacket, just do a small favor for you."
"Isn't It Romantic" hits theaters Feb. 13.
