NEW YORK - Lady Gaga can still play Yankee Stadium -- she's just gotta follow the ground rules.

The outlandish pop singer talked her way past security and visited the Yankees clubhouse after the team lost to the New York Mets on Friday night.

The New York Post reported Sunday that Yankees co-chairman Hal Steinbrenner was upset with Lady Gaga's antics and permanently barred her from the locker-room.

"She's not banned," Yankees general manager Brian Cashman said Sunday. "Celebrities aren't banned. If Michael Jordan showed up here he would have access (to the clubhouse), but not after a loss."

While in the clubhouse, she reportedly drank whiskey while wearing a bikini bottom and a pinstriped jersey that was unbuttoned to reveal her bra. Several Yankees, including Robinson Cano and Alex Rodriguez visited with her.

"That was the wrong time and the wrong place," Cashman said. "It's been taken care of."

Cashman said it was "not her fault."

About two weeks ago Lady Gaga, who grew up a Yankees fan, attended a game at Citi Field and made an obscene gesture while being photographed.
