Patrick Schwarzenegger had a bit of road rage last week, but it seems his car was actually the thing that suffered most.

The famous son of Hollywood royalty, Patrick was in California's San Fernando Valley when someone pulled up next to him, threw a bottle of water on Patrick's car and scurried off. Naturally, this didn't sit well with Miley Cyrus's boyfriend.
