One source even alleged the beauty taught the couple's son to say "Bieber Fever," which didn't sit well with Bloom and which is totally hilarious.
Following reports that Bieber got close to Kerr after a Victoria's Secret lingerie show in 2012, Bloom was spotted hanging out this spring with Selena Gomez, upping the ante in his feud with Justin.
A couple hours after the footage above (which begins after Bieber ducks Bloom's punch and calls him a "bitch"), meanwhile, Bieber took to Instagram and posted a wordless message, clearly directed at his new rival:
Ohhh, snap yo! That's totally Miranda Kerr and Bieber is clearly implied he gave it to her!
Justin later deleted the photo, but the damage has clearly been done to Bloom. The only question that remains: What will happen next?!?
It's unclear how well Miranda Kerr even knows Justin Bieber. But some way she split from Orlando Bloom after he grew tired of his wife obsessing over The Biebs. And you've gotta imagine Justin got on that if he knew about it.
