Apparently, Miley Cyrus and her boyfriend of a year, Liam Hemsworth, have broken up. It’s being widely reported at this point, and I tried to trace back where the stories had come from, because no matter what you read, this split hasn’t been “confirmed” yet. I think this is all coming from the new issue of the National Enquirer – most sources trace back there. Here’s a compilation of the story:

Miley Cyrus is reportedly single again. The teen star is said to have split from her hunk of boyfriend Liam Hemsworth following a huge argument at her Los Angeles home.

The stars, who met on the set of their film The Last Song in 2009, were allegedly living together at the singer/actress’ new mansion in Toluca Lake but Hemsworth is said to have moved his belongings out following a fight last month.

Cyrus apparently grew jealous of Liam’s success after he landed a top role opposite Sir Anthony Hopkins in the forthcoming Arabian Nights.

“The result was a vicious fight — and Liam bolted,” a source told American tabloid the National Enquirer. “He said he’s tired of her folks’ interference, and that Miley’s jealous that his film career has taken off.”

Liam — who was living with Miley at her new mansion in Toluca Lake — didn’t show up to the “Hannah Montana” wrap party and a few days later, moved back in with his brother Chris at the Hollywood apartment they previously shared.

And Cyrus herself appears to have confirmed the romance is on hiatus – when asked by the tabloid about their relationship status, she is quoted as saying, “(We) are on a break.”

The insider adds, “Miley, her family and all her baggage are too much for him to handle.”

Do I buy that they broke up? Sure. I think Miley is probably high maintenance and very-self-involved, and Miley seemed to have zero clue about how naïve she sounded when she started telling journalists that she and Liam were “deeper” than everybody else. I’ll also buy that Liam was probably totally scared off by the Cyrus family. Wouldn’t you? I mean… Trace Cyrus… Billy Ray… Noah… Tish. That family is all kinds of wrong. As for Miley allegedly throwing a hissy fit over Liam’s career… can you see it? Sort of. For all of her big talk about changing and growing up, she’s still a little brat sometimes/most of the time. I can see her being all “You can’t go and work on that film, you’re supposed to be with me!!! All. The. Time!”

However, this does throw her recent comments about Nick Jonas into question – CB reported on Tuesday that Miley had told an audience in reference to one of her super-cool songs, “It’s about two people… They’re always gonna come back together no matter what anyone says or the bad people that try to keep you apart. Surprise surprise, it’s about a Jonas brother…you didn’t hear that.” Yeah… it sounds like Miley wants a little rebound Jonas ass.

Oh, and I bet Billy Ray is thrilled! For real. He hated Liam. Next, The Mullet is going to get Miley to go back on Twitter!
