Miley's new boy-toy apparently has a History Of Violence.

TMZ released some photos Miley Cyrus boyfriend 19-year-old Liam  getting in to a street brawl. Liam Hemsworth is the  brother of  "Star Trek" actor Chris Hemsworth.

Tmz says the fight, which took place several moths ago started after "some late-night smack talk with the random guy. The brothers approached the dude — and suddenly a 2-on-1 brawl broke out." 

The fight  was reportedly broken up by security before the cops came.
