It's just one more occasion where the meat-wearing singer has shown up at a New York sporting events and created a scene, or more accurately, annoyed the fans.
There were no reports of anyone being showered by the bubbly, but it's the third arena where she's worn the home team's hat and acted like a monster.
She has a habit of showing up at New York venues and pulling some stunt, safely, from the security of her luxury box.
Last summer she even riled Jerry Seinfeld enough, after she flipped the bird to fans while sitting at a Mets game at CitiField, that he went public with his annoyance.
The comic was probably thinking: "You ever notice that people who wear food as clothing shouldn't be allowed into sporting events?"
Gaga better not wear the flank steak outfit in the Giants parking lot before a game or it'll end up on some one's grill.
A week after the Mets spectacle, the "Born This Way" singer invaded the Yankees clubhouse swilling whiskey and talking with the players.
At last night's game Gaga wore a bright blue Giants cap to go with her tutu skirt and giant sunglasses.
Apparently, she was celebrating some one's birthday and tweeted about her night.
"@#Giantsgame watching them win like Champions. Touchdown Baby!#GoBlue," she pecked.
The Giants beat the St. Louis Rams, 28-16.
First CitiField, then Yankee Stadium, now MetLife Stadium... Lady Gaga coming to Madison Square Garden soon... and not to sing.
