Justin Bieber, Orlando Bloom Come to Fisticuffs in Spain

A long-brewing feud between pop terror Justin Bieber and usually laid-back screen star Orlando Bloom reportedly led to a knockdown, drag-out fight between the two men in a Spanish club early Wednesday.

The Interwebs went wild overnight, as TMZ unloaded footage of the Lord of the Rings star, 37, allegedly taking a swing at the 21-year-old crooner during a party in Ibiza. Onlookers reported hearing Bieber scream: “What’s up, b!tch?” while ducking under the punch. A number of celebrities were on hand to catch the melee, including Diddy, Lindsay Lohan and Paris Hilton.

Justin left the establishment immediately after the confrontation — but it back to his hotel in time to post a photo of supermodel Miranda Kerr (also known as the almost ex Mrs. Orlando Bloom) on his Instagram. The Biebs captioned the image with an emoticon of a crown. The snap has since been deleted.

Justin’s apparent taunt, however, is telling of the origin of Bieber’s feud with Bloom. Celebrity informants say it dates way back to 2012, when Justin allegedly got too cozy with Kerr during a Victoria’s Secret Fashion Show.

Fun fact: Justin’s ex, Disney good girl-gone-bad Selena Gomez, was spotted in Orlando’s company in April 2014.
