She may have achieved worldwide fame, but Lady Gaga appears to have struck out with the New York Yankees. The singer quickly wore out her welcome with the baseball team when she pulled off her usual shenanigans during a recent game. For starters, Gaga struck a sour note with the team when she showed up to the game in nothing more than a black bra, panties and fishnet stockings covered by a New York Yankees jersey. That's one fashion statement the team could have done without. But Gaga's fun didn't stop there. The "Poker Face" singer became persona non grata when she moved her out-of-control antics into the much coveted Yankees clubhouse. Gaga and two buddies then busted into the clubhouse without an official invite from the team and made a mockery of the ballers. According to the New York Post, Gaga was swigging whiskey and fondling her boobs throughout her 30-minute visit where she rubbed, er, elbows with the likes of Alex Rodriguez and Robinson Cano. Gaga sung her praises for her favorite team while slurring her words. Upon finding out about Gaga's bad behavior, the 24-year-old earned herself a lifetime ban from the Yankees clubhouse by Yankees co-chair Hal Steinbrenner. And this isn't the first time Gaga has made waves at a ball game. She pissed Mets' fans off when she chugged beer and flipped off the Citi Field crowd earlier this month.
