Justin Bieber... The Hero!?

The 24-year-old singer stepped in to help a woman from being attacked by her ex boyfriend at a Coachella party Saturday night (April 14), TMZ reports.

Justin was at a party that night, when a man – who appeared to be on drugs – walked in and went ballistic on a woman believed to be his ex-girlfriend.

Eyewitnesses say the guy was grabbing the woman by the throat when Justin and his pals screamed at the guy to let her go.

When he wouldn’t, Justin hit the guy in the face and pushed him against the wall allowing the woman to break free.

The guy was then kicked out of the party and arrested shortly afterwards.
