Justin Bieber has lots of fans, but Orlando Bloom is not one of them.

Bloom tried to punch Bieber in the face at Cipriani in Ibiza, Spain, early Wednesday (July 30). Video from TMZ shows the 37-year-old actor attempting to push past security to get his hands on Beiber, 20. 

Bieber ducked the swing, but the pop star was ready for a fight at that point. He yelled, "What up b---h?" at Bloom before leaving the nightspot. The crowd reportedly cheered when he left. 

The two were at a party attended by stars like Diddy and Paris Hilton.

Their fight was over Bloom's ex-wife, Miranda Kerr. A source told the New York Post that Bieber made a rude comment about Kerr. However, someone on Bieber's side says he didn't talk about the Victoria's Secret model until after Bloom threw the punch. “Justin was at one table, and Orlando was at another,” an insider said. “But when Bieber and his party were later walking past Bloom’s table, Orlando refused to shake Bieber’s hand.” 

Bieber "said something rude to Orlando, like, ‘She [Kerr] was good,'" and he wasn't done taunting Bloom. Following the run-in, he posted, and then deleted, a photo of Kerr on Instagram.

Bloom's frustration with Bieber could date back to 2012, when she partied with the "Confident" singer after a Victoria's Secret show. Kerr and Bloom, who have a son, split last October.

In April of this year, Bloom was photographed with Bieber's ex, Selena Gomez.
