It’s no secret that Lady Gaga loves nothing more than taking in an afternoon of baseball — while downing a vodka tonic in her undies — but has her boozy misbehavior finally gotten the controversial star banned from her favorite baseball team’s clubhouse?

Gaga attended the Yankees vs. Mets Subway Series matchup on Friday night dressed in underwear, fishnet stockings, and an unbuttoned Yankees jersey. After the team’s 4-0 loss to the Mets, Gaga and two friends made their way into the team’s clubhouse – apparently without approval. The “PokerFace” star — who grew up attending Yankees games with her father — is reportedly no longer welcome in the team’s clubhouse after getting drunk on Jameson Whiskey and fondling her knockers in front of the team.

The bizarre incident came just weeks after the star sparked outrage at a Mets game at Citi Field in Queens, NY by flipping fans the finger in a dispute over her seats. The star then demanded to be moved to comedian Jerry Seinfeld’s sky box, prompting team management to issue a public apology for breaching Seinfeld’s privacy.

Sports snoops tell The New York Post that Yankees co-chairman Hal Steinbrenner is so disgusted at the pop star’s behavior he’s allegedly informed stadium executives that “Skankee” Lady Gaga is permanently banned from the team’s clubhouse.

Team General Manager Brian Cashman, however, denied rumors of Gaga’s ban to ESPN.com on Sunday, telling the site:

“She’s not banned. Celebrities aren’t banned. If Michael Jordan showed up here he would have access [to the clubhouse], but not after a loss.”
