MANHATTAN — She's no lady!
Fuming Yankees boss Hal Steinbrenner has barred Lady Gaga from his clubhouse after hearing she crept in on Friday for a whiskey-swigging, breast fondling performance in front of the Bronx Bombers.
The self-confessed super fan spent 30 minutes with the players - without team approval - after they lost to the Mets, the New York Post reported.


Dressed in an unfastened Yankees jersey barely covering her black bra, fishnet stockings and bikini bottom, the "Poker Face" singer swigged Jameson Irish Whiskey while gushing about how much she loved the club.
But her slurred professions of adoration didn't seem to be getting enough attention. The paper reported Gaga also groped her chest several times.
Her audience was made up of six Yankees, including Alex Rodriguez and Robinson Cano, according to the report.
News of the unannounced show sickened co-chairman Steinbrenner so much he ordered that no encore be allowed.
None of the club's top brass had cleared the singer's visit. Sources told the Post she smooth-talked her way past stadium security with two girlfriends after watching the Subway Series' opener.
The performance was the 24-year-old star's second shocking run-in at a New York baseball game.
On June 10, she flipped off a Citi Field crowd after turning up in the fifth inning and throwing a tantrum because she was seated next to photographers.
She was moved to Jerry Seinfeld's luxury box, where she swilled beers and cursed fans.
