1 of 24Orlando Bloom vs. Justin Bieber
Bloom threw a punch at Biebs in an Ibiza restaurant in July 2014, after which the singer screamed, "What's up, bitch?" The scuffle is widely believed to be over Bloom's then-wife Miranda Kerr, with whom Bieber was seen getting close at the 2012 Victoria's Secret Fashion Show. In April 2014, Bloom was photographed with Bieber's on-again, off-again girlfriend Selena Gomez. After the fight, Bieber posted a bikini-clad photo of Kerr on Instagram before deleting it.
