America's most infamous on-again, off-again lovebirds are feuding again, and this report has nothing to do with the alleged Justin Bieber-Selena Gomez sex tape.
At issue instead is her flirting with Orlando Bloom. Seriously.
Both halves of Jelena are notoriously jealous when it comes to either one of them talking - let alone flirting - with other people. Such is the case here.
Justin Bieber, 20, is said to be furious with Selena Gomez, 21, and her interactions with Orlando Bloom, calling her actions "a slap in the face."
What the Canadian pop brat's girlfriend actually do wrong?
Selena and Orlando recently participated in the We Day California conference on March 26, and were seen hamming it up in Instagram photos.
Photos Justin was none too thrilled about, to say the least.
The singer-actress gave an inspiring speech and later, backstage, posed with Orlando and Seth Rogen, who has been one of Justin’s biggest haters.
The picture, posted to her Instagram account, infuriated Justin, who believed she was trying to rankle him, knowing Rogen's disdain for Bieber's antics.
Seth does not mince words, telling Watch What Happens Live recently that Bieber is "a piece of s--t" ... and "obnoxious and ungrateful and insincere."
According to a source close to the couple, however, it's not just about Rogen. Justin and Selena have been at each other's throats over mutual insecurities.
“Their drama always starts because they don’t trust each other," the insider laments, adding, "It’s not only Selena that gets jealous ... Justin is just as bad."
"He’s the one that started the latest fight. He accused Selena of flirting with Orlando Bloom. He knows that it bugs Selena when he hangs out with Miley [Cyrus]."
"So, of course he wanted her to know about it ... because he’s feeling insecure and he wants to make her feel the same way [as he felt about Bloom]."
Well, that sounds really mature all around, you guys. Well done.
Just imagine when he inevitably gets Selena Gomez pregnant. You think they have issues now? Things are only going to get more insane, THGers.
