Gaga goes cuckoo! The singing sensation lost it at a baseball game, stripping down to her bra and glittering panties and cursing out fans and photographers!
So what sparked Gaga's tantrum?
Her front row seat was right behind home plate, giving photographers covering the game a clear shot of her. That's when she flipped out.
She stripped down to a bra and bikini bottom, and then, as the crowd of 32,000 started booing, she made obscene gestures.
Stadium officials moved her out of sight, to a private box owned by comedian Jerry Seinfeld.
Gaga's baseball flip-out came just one day after she showed up at her sister's high school graduation in an outrageous outfit, including a beekeeper's hat and see-through pants.
