Since announcing their engagement earlier this month, Miley Cyrus and Aussie actor Liam Hemsworth have been battered by claims that they're too young to wed.

But if our exclusive interview with former tween idol Miley Cyrus is anything to go by, it seems the couple knows just what they're in for when it comes to married life — and they can't wait!

Speaking exclusively to Woman's Day last night at the Australians in Film Awards in Hollywood, where Liam, 22, picked up the prestigious Breakthrough Award, Miley revealed, "We just both love our lives together — and that's what makes us both really happy right now."

The 19-year-old couldn't stop gushing about her future husband, adding, "He really cares about what he does and he doesn't really care about the fame part which is exactly what I feel too."

She admits she knew from a young age exactly what she was looking for in a man — mainly thanks to the values instilled in her by her father, 'Achy Breaky Heart' singer Billy Ray Cyrus.

"My dad's always been a really hard worker so I like men who work hard," she says. "I think it is really important to me because I always work really hard so it's good to be with someone who is equally passionate. We don't just want things to be OK — we both give everything 130 percent."

Of course, Miley, who beamed that she's "super stoked" about her beau's award, is the first to admit that it helps that her fiancé is easy on the eyes.

"Aussie guys are way hotter than American guys — there's no competition!" Miley says with a cheeky grin. "There's a masculinity about him — it's probably like growing up in the south like I did. He's very respectful and you know — he's not bad looking either!"

Discussing her beau's Aussie award, she couldn't hide her pride. Clad in a revealing black cut out dress by Australian designer Zimmerman, she told Woman's Day: "I love something with a built in corset — every girl does! Liam was there when I picked it out and he loved it."

Of course the dress we really wanted to talk about was her wedding gown — and get the answer to the all-important question of where they'll wed — down under or in Miley's native Tennessee.

But Miley dodged the question, telling us, "I'm not ever saying anything about where the wedding will be!"

And when we asked Liam he was giving nothing away either, saying only, "We'll have to wait and see on that one."

But later in the night, Liam shared juicy tidbits about their life while mingling with guests– drawing a collective "Aww!" when he revealed how much he loves Miley's 3.5 carat, custom-made Neil Lane engagement ring.

"I was with her when she chose it," he explained. "I never thought I would care about jewellery but we went outside and the way it sparkled on her finger in the sunlight — I knew that was the one."

He also revealed in his award acceptance speech that four years ago, when he first came to LA, he suffered a string of setbacks over a three-month period and was due to return home to Australia in just one week. But that's when he landed the chance to audition for his first big film called The Last Song. He scored the male lead in the tear-jerker, which not only provided the springboard for his career but also introduced him to his co-star and future fiancée Miley.

"That audition changed my life because I got the part and fell in love and now we're going to get married.

"People told me to just keep things professional but we didn't," he says. "And I'm so happy we didn't!"
