Did the Henries start a Huge Fight?

Rumors on the net suggested that a physical fight broke out at Universal City Walk this spring where David Henrie and his brother Lorenzo were attending a party for Gregg Sulkin. That part's true, but David tells Popstar! that he and his brother were not to blame. Apparently, Lorenzo made a joking comment about a nearby group being too loud, the reacted angrily and then security staffers responded by aggressively restraining the Henries. It was a nightmare scene for people to witness (many sent their reports to HollywoodLife.com) and for the Henries to live through. Be careful, guys!
