Justin Bieber vs. Orlando Bloom FIGHT Video, 'What's Up B*tch!' Miranda Kerr's Ex 'Throws Punch' In Spain, Singer 'Flees' - Selena Gomez 'Beef' Brewing? [WATCH]

Justin Bieber once flirted and allegedly "hooked-up" with Victoria's Secret babe, Miranda Kerr (the ex-wife of popular actor, Orlando Bloom). Several months later, the "Pirates of the Caribbean" star was spotted "cozying-up" to the Biebs' former sweetheart, Selena Gomez. So, did such girlfriend drama prompt a huge celebrity feud?

After watching this rather heated confrontation between 20-year-old Bieber and 37-year-old Bloom in Ibiza, Spain, that answer would definitely be yes!

According to TMZ, Bloom "threw a punch" at the "Believe" crooner when the two butted-heads at a restaurant early Wednesday morning (July 29). According to eyewitnesses, Bieber then fled the restuarant (called Cipriani). Several other celebs were also there, including Paris Hilton and Diddy.

The attempted blow isn't caught on tape, but sources insist that Bloom did try physically "attacking" Bieber. The infamous pop sensation ducked the hit, and then exclaimed, "What's up b*tch!?"

When JB left, onlookers apparently applauded.

Do Mstars fans believe the two Hollywood heartthrobs were feuding over their past leading ladies? Stay tuned as more details develop...
