Miley Cyrus, Liam Hemsworth Split? Starlet's 'Wild Partying' too Much to Handle, 'It's Over': Actor Jets to Australia Following Cheating Rumors

Rumors have been swirling for weeks that Miley Cyrus and fiance Liam Hemsworth's relationship is most definitely on the rocks... and now several reports confirm that the young couple has officially split for good. Following shady allegations that the "Hunger Games" heartthrob cheated on Cyrus with "Mad Men" sweetheart January Jones, the 20-year-old starlet was spotted out in public without her engagement ring on several occasions. Soon after, Hemsworth jetted off to Australia to spend some time with fam... solo. Now, a recent New York Post Page Six report claims that Cyrus' wild, hard-partying ways just became too much for Hemsworth to handle... it's over, for good (apparently).

An alleged inside source reveals to the Post, "Miley and Liam are done; it's over. She likes to party really hard and can be pretty wild. It became a problem for him."  

The insider goes on to explain, "They have broken up before, and are broken up again now. There was drama because she suspected he had a wandering eye. And she recently tweeted a denial that he cheated." Another source adds, "While Miley has insisted they are still together, right now they are very, very much apart." 

Here's the original story, as Mstars previously reported:

Despite recent rumors that Liam Hemsworth was spotted "kissing and flirting" with "Mad Men" starlet January Jones, inside sources confirm that the "Hunger Games" heartthrob and pop songstress Miley Cyrus are indeed STILL engaged. In fact, the couple's extremely happy and there's been no relationship "drama" as far as their concerned. So fans can now breathe a slight sigh of relief, all those cheating rumors are completely false.

The cheating allegations started brewing Saturday night (Feb. 23), when Hemsworth was spotted partying with Jones at Grey Goose's exclusive pre-Oscars event at the luxurious Chateau Marmont - with Cyrus nowhere in sight. One "eyewitness" allegedly told Star magazine, "It looked like they had some hot chemistry.They were all over each other - and they even kissed! Liam got January's coat and helped her put it on, then they headed outside. They made sure to leave a few seconds apart, so they wouldn't attract too much attention. Then they jumped into a waiting car and took off."

Things didn't look so good in paradise when Cyrus showed up to Elton John's annual AIDS foundation Oscars viewing party on Sunday... with her mom, Tish. Hemsworth did not attend.

But no, the couple isn't "on the rocks" or "on the verge of separation" - at least not according to an inside source for E! News. The unnamed pal claims, "They are still together." The insider goes on to explain that there's definitely "no drama" even though the couple spend the Oscars weekend apart. Cyrus' mom Tish really wanted to go to Elton's event - so that's who the former "Hannah Montana" star took. All the rumors (including the shady cheating accusations) just aren't true. And to reiterate again, the duo's engagement is still most definitely ON.

Cyrus eventually got sick of all the rumors, and took to Twitter to express her anger and annoyance. She also reiterated the fact that her engagement is still on:

@MileyCyrus: "I am so sick of La. And sick of the lies that come with it. I didn't call off my wedding. Taking a break from social media. #draining."

She then promptly deleted her account.

Fans would think that settles things... but Cyrus stirred even more drama when she stepped out Wednesday night sans engagement ring. Check out the TMZ photos here.

But now the rumors have completely turned once again... Cyrus did eventually re-activate her Twitter account,  but has yet to comment on the break up allegations:

@MileyCyrus: "not discussing anything but my music from now on."

The former "Hannah Montana" starlet is currently working in LA - Hemsworth flew down to Australia earlier this month for a little "break." An insider for People magazine confirmed at the time, "It doesn't mean that they have split. Miley says they are still together. Liam did fly home [to Australia on March 1] so they could have a break." 

So many conflicting stories... do Mstars fans believe that things are really over between Cyrus and Hemsworth?
