As Beliebers everywhere continue to celebrate the break-up of Selena Gomez and Justin Bieber with ritual dances to their various gods, news is trickling out about their first ever split over another girl.

No, it's not a Victoria Secret model who caused this one. It was supposedly Miley Cyrus.

Prior to their bust-up last week, tensions were high between Gomez and the Biebs over his March 2012 stint with Miley on 'Punk'd.'

According to a dubious source, “Selena is repulsed by Miley!” (Hey, so is the rest of the world, but you don't see us complaining about it to online gossip outlets.)

Gomez aired her concerns to Bieber about his appearance with Cyrus, but he pushed them aside and filmed the show anyway. Possibly so they could settle once and for all whose hairstyle is the least attractive.

His actions were not well-received by Gomez, who, tired of playing second-fiddle to everyone and everything in Bieber's life, broke it off with him.

"He's been continually choosing work over Selena and she's finally had enough," the source alleges.

At least that time she didn't blame it on "scheduling conflicts."
