Gaga safe at home

Yankee General Manager Brian Cashman is gaga for Gaga — saying yesterday that the half-dressed singer did nothing wrong when she infiltrated the players’ clubhouse after a game over the weekend, causing a stir among team brass.

Instead, Cashman put the blame on his own employees for allowing the outrageous “Poker Face” singer to make her uncomfortable, boozy visit to the clubhouse Friday night after the Yanks’ Subway Series loss to the Mets.

“She didn’t do anything wrong,” Cashman said.

The GM said celebrities are allowed to mingle with players in a designated area adjacent to the locker room — but only after Yankee victories. They are not usually allowed in the clubhouse, he said.

“She’s not banned” from Yankee Stadium and the VIP area, Cashman said.

The player-celeb issue came to a head after Lady Gaga infuriated Yankee brass with her antics in the clubhouse Friday night.

A liquored-up, half-naked Gaga could barely string together coherent sentences as she fawned over several players near the locker room — causing team co-chairman Hal Steinbrenner to become unglued and ban the singer permanently from the team’s clubhouse, according to sources close to the boss.

Gaga’s pals and rent-a-cops walked right past Yankee security on their way into the clubhouse.

Gaga was wearing an unbuttoned pinstripe jersey over her bra and bikini bottom — and nothing else — as she struck up conversations with some of the Bronx Bombers. She gushed about what a Yankee fan she is, all while groping her breasts during the cringe-inducing visit.

A rep for Gaga did not return a call for comment.

Cashman said the team would step up enforcement of its existing clubhouse rules, which limit VIP access to players to a mingling area adjacent to the locker room.

“There is a time and a place for that, and it’s certainly not after a loss and not at the expense of the media doing their job,” Cashman said.

It was the second time in a little more than a week that Gaga — whose real name is Stefani Joanne Angelina Germanotta — has caused a silly stir at a New York stadium.

During a visit to Citi Field on June 10, the singer showed up in the fifth inning and flipped out when Mets personnel escorted her to front-row seats — too close, for her liking, to sports photographers shooting the game.

When she was then escorted to the empty luxury box of Amazin’s diehard Jerry Seinfeld, the classless songbird went nuts again, cursing out fans and giving twin-fisted, middle-finger salutes to the Flushing faithful.
