Justin Bieber's tiffs with the paparazzi are pretty well-known, but we never expected him to get into a full-blown fight with another celeb. According to footage found by TMZ, Orlando Bloom and Justin got into such a heated argument that Orlando tried to take a swing at Justin the Ibiza restaurant!

While we knew there was some tension between Justin and Orlando after Justin accused Selena Gomez of flirting with him, we had no clue things would actually get physical. Justin's bodyguards seemed to diffuse the tension, and who knows what would have happened if they weren't there?

Still, Justin seemed unfazed by the fight, even tweeting that he was keeping things positive.

But their argument got pretty heated, so we wonder exactly what they were fighting about. Shockingly, Selena might only be part of the reason that they had such an intense encounter!

After their argument, Justin posted and then deleted a bikini pic of Orlando's ex-wife Miranda Kerr on Instagram. That definitely seems like a not-so-subtle jab at Orlando, especially because Miranda and Justin have been pretty cozy in the past.

Can you believe that Orlando tried to punch Justin? Why do you think they're fighting? Tell us in the comments!
