Justin Bieber and Orlando Bloom

But you can’t talk about celebrity fights without talking about one of the most infamous of all. Justin Bieber once had his eyes on Orlando Bloom’s (now ex) wife, Miranda Kerr. When Kerr and Bloom were in Splitsville, she started hanging out with Justin. When Justin Bieber came face to face with Orlando Bloom at a club, he taunted Bloom, saying very derogatory things about Bloom and Kerr’s relationship. Bloom punched Bieber in the face and when Bieber left the club, the whole club applauded.
