The war is definitely on between Justin Bieber and Orlando Bloom who are allegedly caught in a brawl in Ibiza, Spain hours after he posted a picture of the actor's ex-wife on Instagram. Kerr's hot bikini pic was immediately took down but a gossip site was faster to capture the post as the singer took social media to fight back with the actor who reportedly threw a punch at him.

"Wow, Justin - this is bold! Just hours after an alleged scuffle in Ibiza, Spain, with Miranda's ex Orlando Bloom, Justin posted a photo of the Victoria's Secret model in a bikini," Hollywood Life reports. "Justin captioned the sexy pic with no words, but just a crown emoji. The emoji looks JUST like the tattoo Justin has on his chest!"

A bold retaliation from the "Baby" singer, the two stars have long reported history together that involves each of their exes, Selena Gomez and Miranda Kerr. Their old conflict started when the Canadian singer texted the Victoria Secret model while she was married to the "Pirates of the Caribbean" star in 2012. The two got pretty close after a 2012 Victoria Secret fashion show in NYC.

Now fast forward to 2014, Bloom was spotted many times with Selena Gomez and was rumoured to be dating the singer/actress. Some reports are speculating that the alleged fight of the two stars stemmed from their past relationships.

The fight happened early Wednesday morning in Ibiza's Cipriani restaurant and according to witnesses Orlando started the fight first. "You don't see Orlando swing, but the eyewitnesses tell us that's exactly what happened," TMZ reports. "We're told Justin ducked the punch. That's where the video starts and you hear Justin scream, "What's up bitch?"

The gossip site claims that Bieber left the scene of the drama applauded by the crowed and updated their report with a new video where "Bloom deliver a right hand shove to Bieber's face, though Bieber's bodyguard appears to deflect the brunt of the blow."

Bieber is currently in two years' probation for an egging event that happened earlier this year and was tasked to complete anger management classes and five days of community service on time. He accepted a plea deal after he pleaded no contest to misdemeanor vandalism.
