We're sooo confused about what's going on between Miley Cyrus and fiance Liam Hemsworth, but there is one thing he's been committed to through all of this ... the gym!

On Monday afternoon the Aussie hunk was snapped post-workout in Los Angeles, and he didn't have much to say, but then again, how can you top that awkward grunt/moan he gave us the other day when asked about his relationship status?

Over the weekend Miley shot her music video in L.A., and on the first day of shooting she was wearing her diamond engagement ring, but on the last day her fingers were bare. What do YOU think is going on with these two?

Liam Hemsworth headed to a personal training session today, and the actor must not have wanted to talk about his reported broken engagement with Miley Cyrus, because he opted to grunt and make obnoxious noises when our photographer questioned him about the split!

The Aussie hunk has been working out nonstop lately! Just yesterday, the Hunger Games star headed to a local gym to pump some iron, so either he's working off some relationship stress or getting his bod in tip top shape now that he's single and ready to mingle!

Check out the full video to hear Liam's bizarre reaction...

So much for that bushy beard he was growing!

On Monday afternoon Liam Hemsworth was spotted on set in Los Angeles, and we're not 100% sure, but based on his hair and preppy clothes we think it's re-shoots for Paranoia. And speaking of paranoia, what's all this fuss about Liam and Miley Cyrus' wedding being off?

Despite rumors last week that Liam's brothers had staged an intervention in an attempt to get him to break things off with his fiancee, a source close to the couple tells E! News that the wedding is still on and it's simply a matter of the two wanting to take their time before walking down the aisle.

The insider added that the Hemsworths have been "very welcoming to the entire Cyrus family."

Liam Hemsworth hit the gym on Monday, and when X17 photographers snapped him on the way out, we got a peek at his freshly shaven face. Well, sort of ... he wasn't clean cut like his character in The Hunger Games, but there's definitely less scruff now than there was the last time we saw him!

Maybe Miley Cyrus prefers her man a little less furry? Despite reports that the two have been on the rocks lately, Miles has been wearing her engagement again, and she recently told Elle UK that "it just seems right to be wearing this ring and to be committed."

It seems like the shorter Miley Cyrus' hair gets, the longer Liam Hemsworth's beard grows! Maybe miss Miley prefers her fiance with a little extra scruff?

Liam hit the gym in Hollywood on Monday afternoon, and we haven't seen him with Miles since he returned to the states last month. According to Life & Style, the lovebirds are still together, but they've postponed their wedding. "They were supposed to get married in June. But there have been so many problems with them, they thought it was best to work out their issues before making such a big commitment," a source told the mag last week.

All Miley's been tweeting about lately are her new songs, and after partying it up in Miami last week, we're not sure what to think of their relationship. Think all's well with these two?

And speaking of her music, Miley's new track with Will.i.am, "Fall Down," leaked last night ... check it out below and let us know what you think!

Does this mean there's still hope for Miley Cyrus and Liam Hemsworth?!

After reports surfaced that Liam cheated on Miley with January Jones at a pre-Oscar bash last month, the Hunger Games hunk left for Australia to give his fiancee some space. Liam was spotted at Ninoy Aquino International Airport in Manila, Philippines today to promote a clothing line he endorses, but while he's been gone his vintage teal Mach 1 Mustang has been sitting in the driveway of Miley's Toluca Lake mansion. Surely he has his own garage space, and if Miley and Liam were REALLY broken up, do you think she'd let him keep his ride there? Nope ... she'd probably be pulling a Carrie Underwood and vandalizing the crap out of it!

“[Miley and Liam] have been a bit rocky, but are not giving up,” a source told E! News the other day. “They both want it to work.” Seems like that could be right! But will things ever be the same between the lovebirds?

Miley Cyrus' mystery man -- the guy she partied with last night and drove home with in her Porsche Cayenne -- is a boy named Paul Khoury, from her gang of friends.

Could Paul be Miley's revenge date after reports fiance Liam Hemsworth hooked up with January Jones surfaced earlier this week? Or was last night's outing just two friends, innocently hanging out ... without Liam?

We know Paul went to Palm Springs with Miley and Liam and a gaggle of friends last September but we haven't spotted the New Jersey native with Mr. and Mrs. Cyrus in our own archive of X17 pix.

And of course you'd expect Miley to address the whole thing on Twitter, 'cause you KNOW she's seen our story and our photos today. And she did! Well, we think she did ... kinda ...

Deep.

Meanwhile, Liam's in Australia, having jetted off to his home country a couple weeks ago to give Miley some breathing room, according to People.com.

"Miley is still upset with Liam. She took off the ring to make him mad," a source tells the mag. BUT, "It doesn't mean that they have split. Miley says they are still together."

Say it isn't so!

Miley Cyrus' fiance Liam Hemsworth has apparently betrayed his lady love with none other than January Jones!

The Hunger Games actor and the Mad Men actress got cozy at a Grey Goose pre-Oscar bash, according to Life & Style.

The pair supposedly enjoyed a steamy makeout sesh!

"They went to a private house party, and right in the middle of the party, January was clinging to Liam, saying, 'You're so handsome.' He kept saying, 'We can't do this here.' Then they left holding hands and went out in the hallway and were making out. She was wasted. It wasn't good," a source tells the mag.

So how does the Hannah Montana star feel about the rumored infidelity?

"Miley is freaking out. She's been telling her friends that she trusts him but if she finds out the cheating claims are true, the engagement is over," the source adds.

This doesn't sound good!
