Gaga took to Twitter to express to share her excitement.
"I can't even believe my best friend and I thought this would be a good idea at 10:45 in the morning after a night none of us can remember," Gaga captioned on Instagram with a video from the workout.
"Bachelorette weekend hungover pole dancing class! Somebody get that Popstar a hairbrush!," she added.
Gaga, 28, has been dating Taylor Kinney for more than three years.
