Justin Bieber Disses Orlando Bloom, Selena Gomez 'Flirts' With Nat Wolff After Epic Ex-Boyfriend Fight? [WATCH]: Miranda Kerr Instagram 'Love' Prompts 'Needs To Be Put In Place' Feud

Justin Bieber and Orlando Bloom are definitely NOT friends - and it all has to do with jealously involving ex-lovers Selena Gomez and Miranda Kerr!

As Mstars previously reported, 20-year-old Biebs and the popular English actor got into a rather heated altercation in a Spanish restaurant earlier this week:

And the "Boyfriend" singer just couldn't let things rest - he later posted this Instagram photo of Bloom's stunning (soon to be) ex-wife flaunting a sexy bikini:

The snapshot was quickly deleted - but pretty low-blow, right? Rumors initially suggested that the couple broke-up because Kerr couldn't stop flirting with the Biebs...

Meanwhile, 22-year-old Gomez seemingly ignored such drama by enjoying herself at the movie premiere of "Behaving Badly." She cuddled-up to co-star Nat Wolff on the red carpet:

selenagomez: "Aw that was fun. I tried to give my self a "tattoo bracket". Don't ask. My Nat! but I miss Alex. Hi Alex!"

The two are just close friends, but would they actually make a cute couple?

Considering Gomez and Kerr weren't even directly involved, why did Bloom attempt to "attack" Bieber? According to an alleged HollywoodLife.com insider, "The Hobbit" star is a rather peaceful person, but still thinks the young singer "needs to be put in place" -

"Orlando is not a violent person. In fact, he's all about promoting peace... However, he will not tolerate a person, Justin Bieber included, who doesn't respect women. He thinks Justin needs to be put in his place and Orlando is well aware that Justin has badmouthed him before."

Another source claims that Bloom immediately regretted his rash actions, although Bieber apparently "initiated" the fight:

"...In mid-throw Orlando realized what he was doing and pulled back, making it look awkward and something that didn't connect."
