Did Miley Cyrus Come Between Selena Gomez + Justin Bieber?

It's almost a given that Disney stars come with drama, and even when they leave the Mouse House, it still seems to follow them. Case in point: Selena Gomez and Miley Cyrus. In light of Selena and Justin Bieber splitting up, rumors are circling that Miley may have had something to do with it -- but not in the way you'd think.

Radar Online reports that when Biebs punked Miley on MTV's 'Punk'd' back in March, it was the beginning of the end for Jelena. "The first time Justin and Selena broke up, it was because Justin shot an episode of 'Punk'd' with Miley Cyrus," a source said. "Selena is repulsed by Miley!" Harsh, Sel! We're guessing this all stems from their feuding over Nick Jonas back in their Disney days (in which case we say the two of them need to move on -- they're not children anymore).

"Justin did the show anyways, which didn't sit very well with Selena," the source added. "He's been continually choosing work over Selena and she's finally had enough."

To be fair to Biebs, a job is a job -- and teen pop stardom can fade in the blink of an eye. We can't fault the guy for capitalizing on his fame while he has it. And dude, that 'Punk'd' episode was hilarious!

The source confirmed that the split was partly due to their schedules, but also due to Sel's trust issues, which have only grown over time as Biebs has grown up in the public eye. "When they originally started dating, Justin was a boy entertaining young girls, and now he's a man surrounded by Victoria's Secret models, and Selena doesn't like that."

Bieber was surrounded by Victoria's Secret models because he was performing at their fashion show for work. Sure, it's every man's dream job, but still! Sel, the boy adores you. Believe him! (Maybe she does.)
