Lady Gaga looked like she was hittin’ a club instead of Tony Bennett‘s 90th birthday tribute — still, we’re willing to bet there were no complaints.
Gaga showed up to Tony’s birthday celebration Thursday night at Radio City Music Hall with a see-through black dress … hiked right up to her crotch.
She looked awesome, but that’s a dangerous outfit to wear around the elderly.
