Boys will be boys! And of course they were fighting about girls...

Justin Bieber, 20, and Orlando Bloom, 37, reportedly got into a fight early Wednesday morning inside of Cipriani restaurant in Ibiza, Spain, and according to TMZ, Orly was the one who threw the first punch! But did the Biebs and his big mouth start it? Maybe...

Apparently Justin was talking smack, at which point Orlando approached and attempted to strike the singer. Justin ducked to avoid getting hit and yelled, "What's up b*tch?" before swiftly exiting the restaurant.

While the Biebs partied with Orlando's ex-wife Miranda Kerr in 2012 after the Victoria Secret Fashion Show, Orlando seemingly took things one step further when he got all flirty with Justin‘s ex Selena Gomez last April.

But was this fight about both of the ladies or just Miranda? A few minutes after the squabble, Bieber posted an Instagram photo of Miranda in a bikini with a crown symbol as the caption. He deleted the pic a few seconds later, but it makes us wonder what really went down between the Aussie supermodel and the Biebs...
