Model Nicole Fox had a terrifying encounter with a stranger outside her Los Angeles home on Thursday morning (07Mar13), just hours after ringing in her 22nd birthday with family and friends.

The former America's Next Top Model winner, who has gone on to feature in campaigns for Nicole Richie and Steve Madden, was left bloodied after an unprovoked street attack.

Fox posted a photo of herself nursing a bang to the head and a cut arm on, writing, "It's not every day you are assaulted by a grill-wielding stranger outside of your apartment on your birthday. My 22nd year is bound to be One Hell Of One."
