GOING GAGA: Lady Gaga stands for God Bless America during the seventh inning stretch as the New York Yankees play the New York Mets in a baseball game.

Comedian Jerry Seinfeld doesn't see the funny side about Lady Gaga's outlandish behaviour during her recent outings at a couple of baseball games.

"This woman is a jerk. I hate her," Seinfeld said during a radio interview. "I can't believe they put her in my box, which I paid for."

Lady Gaga attended a game between the San Diego Padres and the New York Mets at Citi Field in New York earlier this month and was photographed flipping the bird.

She was reportedly unhappy with her front-row seats, which were too close to the photographers, and later reappeared in the vacant luxury box owned by Seinfeld.

"You give people the finger and you get upgraded? Is that the world we're living in now?" the 56-year-old comedian said.

"I don't know what these young people think or how they promote their careers."

Last weekend Lady Gaga rocked up to a New York Yankees' baseball game wearing fishnet stockings, a bikini bottom and a pinstriped jersey unbuttoned to reveal her bra.

She was reportedly seen swigging whiskey, slurring her words and fondling her breasts while trying to meet players.

"I'm not one of these all-publicity-is-good people. People talk about you need exposure - you could die of exposure," Seinfeld said.

"She is talented, I don't know why she's doing this stuff."
