Lady Gaga clearly doesn't know how to act when it comes to attending sporting events in New York City. First, there was the infamous incident involving her flipping off the crowd at a Mets game. Then, she nearly got herself banned from Yankee Stadium forever after she made a bizarre trip to the Yankees clubhouse. And last night during the Giants game at Met Life Stadium in the Meadowlands, cameras caught her dumping out an entire glass of champagne during the fourth quarter before making a quick exit from the luxury box where she was sitting.

Yo, Gaga: Is it too much to ask for you to just sit and—oh, we don't know—watch the game? Nah, that's just crazy, right? [via Terez Owens]
