Patrick Schwarzenegger was using a fake ID Saturday night at The Sayers Club but that wasn't what prompted nighclub bouncers to give him the boot.
Former California governor Arnold Schwarzenegger's 19-year-old son, a male model and aspiring actor, was partying with friend at an L.A. hotspot when he started tossing ice cubes at the DJ.
The USC freshman was asked several times by DJ Anthony Valadez to quit bumping his electronic equipment. This apparently annoyed Maria Shriver's son -- who escalated matters by throwing ice.
A sharp-eyed cocktail waitress recognized Patrick and alerted the security team that he was the son of famous parents and happened to be underage.
After a bouncer put the run to Schwarzenegger and his friends, they carried on loudly on the sidewalk with offensive language that was captured by TMZ.
Patrick hit Twitter earlier today with a vague message of regret, "Excuse my language. I apologize." A few hours later he added, "Live and learn, hope everyone has a blessed day."
