Liam Hemsworth laughed off rumors that his girlfriend Miley Cyrus is jealous of his "Hunger Games" fame on Friday.

The actor, who portrays Gale Hawthorne in the new film, is just getting used to the fan frenzy but told "On Air with Ryan Seacrest" that Cyrus is happy for him.

"She's one of the biggest stars in the world, there's no shadowing her," Hemsworth told Seacrest. "She embraces it, she's very very happy for me. I've had a few marriage proposals from 12 year old girls! It's really an awkward question to get a marriage proposal from someone you don't know at all, and who doesn't know you!"

The 22-year-old Australian actor plays Gale Hawthorne, the best friend of heroine Katniss Everdeen, portrayed by Jennifer Lawrence. In "The Hunger Games," Everdeen lives in a post-apocalyptic future where a boy and girl from various districts are chosen and taken to a massive area where they must survive and fight to death.

"When I read the books I always connected to my character more," Hemsworth said. "I always thought that I could play him the best. The thing about Gale is that he is extremely passionate about not siding with these games. He doesn't want to be a part of them. He's trying to fight back. He's trying to find a way to get away from it. I thought that if I was in that situation that I would do the same thing."

"The Hunger Games" is based on a book series by Suzanne Collins. The stories already have a fan following, mostly among teenage girls, and hundreds attended the Los Angeles premiere earlier this month.

Hemsworth attended the event with Cyrus, who was his co-star in the 2010 movie "The Last Song."

At the premiere, E! Online asked Cyrus what the hardest part of filming "The Hunger Games" was for her boyfriend. She quipped, "I think the hardest part for Liam was being away from me... And his brother and his family. At least he's not in a tour bus and is in a nice hotel somewhere. It's a little less bumpy, a little more sleep."

Hemsworth didn't seem to be getting much sleep during "The Hunger Games" world-wide promotional tour though. After opening in Los Angeles, New York, London and Paris, the stars returned home in time for what promises to be a record-breaking opening.

"I haven't slept in probably three weeks... Just running on adrenaline most of the time," Hemsworth told Seacrest of the promotional schedule. "It's kind of finally here. I've been waiting a while for people to see it, and I've been talking about it a lot. The expectation just keeps getting bigger and bigger. I'm really excited for people to see it."
