Miley Cyrus' fiance, Liam Hemsworth, is already drop-dead sexy, but throw in a vintage 1969 Ford Mustang Mach 1, and the Australian hunk just got even hotter!

After leaving Starbucks, the 22-year-old Hunger Games stud and a pal cruised the streets of Calabasas in his bright $100K muscle car.

Australian muscle enjoying some American muscle ... loves it!

Liam Hemsworth appeared on Good Morning America to promote his latest flick The Expendables 2, however talk quickly turned to fiancee Miley Cyrus' new short haircut.

When asked what he thought of her 'do, Hemsworth responded, "Her hair looks great, it's a big change, it looks really fantastic."

Good thing he's supportive. And yes, Miley is continuing with her daily Twitpics showing off her funky fashion sense. Check out the latest one below.

Now we know why he popped the question!

Liam Hemsworth covers the latest issue of Men's Health magazine, and the hunky Aussie actor couldn't help but gush about his Disney star fiancee Miley Cyrus during the interview!

"She's an extremely strong, intelligent, supportive person," he explained about his love of three years.

The 22-year-old also revealed that he surfed competitively in his native Australia before making it big in Hollywood. "I wanted to surf for the rest of my life. It's what all my friends did. I even had it as a subject in school for a number of years," he confessed of his love for the sport.

His lady love is now famous for her hot Pilates body, so does the Snow White and the Huntsman actor share her passion for fitness?

"I love going to the gym, sweating, running around, feeling like I'm having a heart attack. I like the physical side of boxing - it's fun to punch a bag for 20 minutes - but I also feel mentally strong when I box, I feel good in my own body."

With a body like that, we can see why!

Good thing Liam Hemsworth is just acting!

Miley Cyrus' fiance, who happens to be shirtless, is getting hot and heavy with his Love and Honor co-star Teresa Palmer.

The film is described on IMDB as the following: "When a young soldier in Vietnam (Austin Stowell) gets dumped by his hometown girl (Aimee Teegarden), he and his best friend (Hemsworth) decide to go AWOL and return to the States to win her back."

Good thing Miley and her svelte yoga body are extremely secure!

You know what they say... a couple that plays together, stays together!

Miley Cyrus and her fiance Liam Hemsworth took advantage of the California heat today and went skating around their Toluca Lake neighborhood. The former Disney starlet upped temperatures in mini jean shorts, a grey tank, and girlie pink Vans sneakers. Not to be outdone by his lady love, The Hunger Games actor sported a blue beanie, Converse, and a white tank that showed off his muscles.

These lovebirds seem to prefer a low key valley lifestyle! We always spot the engaged pair on walks with their many dogs, so it doesn't surprise us they've decided to venture into street surfing together.

Maybe the mysterious marks on Miss Miley's arms were just a bad case of road rash caused by a nasty spill on the pavement?

Is that Miley Cyrus on the phone?!

Liam Hemsworth stopped to take a call on his cell in Toluca Lake yesterday, and the hunky The Hunger Games star looked to be grabbing his package while he chatted away! The Aussie actor put his muscles on display in a tank top and athletic shorts, and it appears he's trying to give his fiancee a run for her money in the body department!

For those that think the 22-year-old is just Mr. Miley Cyrus, think again! The future Mrs. Hemsworth could not be more thrilled that her man has become a star in his own right, telling German InStyle magazine, "I am very happy that he is so successful with The Hunger Games. I think, it is good for him if he is not only seen as 'the boyfriend of Miley Cyrus' all the time. It can be beneficial for our relationship as we are on the same level now."

No wonder Liam put a ring on it!

Liam Hemsworth is a true gentleman!

The Hunger Games star and fiance Miley Cyrus were spotted grabbing some grub in Toluca Lake today, but instead of letting his main woman tread through the LA heat, he opted to go get the food solo while she waited in the car. Now that's love!

The two seem to be as close as ever despite rumors of them having second thoughts on their engagement. Liam just got back from NYC after filming scenes for his next project, Empire State, while Miley's name has been thrown into the hat to become American Idol's next judge, so these two are too busy to indulge in the gossip!

Miley Cyrus is the proud owner of a 3.5-carat cushion-cut Neil Lane diamond engagement ring, according to People.

Neil Lane, who says Hemsworth wanted "something unusual," tells the mag:

“It was hand-cut around 1880 or 1890 and it’s unique and in its original form,” Lane says. “At that time no two diamonds were alike, as they were all hand-cut, so it’s fascinating to look at because it hasn’t been re-cut to look contemporary over the years. I find that really romantic.”

The Hannah Montana star is beyond thrilled with the handcrafted 18-karat gold creation! Miley Tweeted, "Thank you for all the love today. I’m happy to share this news with you all. I feel like all my dreams are coming true.”

Lane adds, "It’s a contemporary design based on vintage aesthetics. The light flashes and sparkles no matter where Miley moves her hand.”

Liam proposed to Miley on May 31.
