The flamboyant singer also said she can dance topless because her pals don't let her get caught.
The 26-year-old said: "I'm a complete free spirit, so, even though you don't see it, I still find time to have sex at night on the beach when no one's around."
The Poker Face singer added: "Or roll into a bar and get up, and dance with my top off. It's just that no one ever sees that, because I have great real friends who never let me do it when I would get caught."
Her beach-sex revelations will not come as a complete shock — as Gaga recently shared a photo of what looked like a naked embrace with boyfriend Taylor Kinney with her fans.
But the singer did tell the magazine the she sometimes struggles to get a handle on the real world.
She said, "I hate the truth so much that I would prefer a giant does of bull any day."
