The 'Born This Way' singer, who is dating Vampire Diaries star Taylor Kinney, said that she lives her life as a "free spirit" a lot of the time and is able to do so because her friends are so protective.
The iconic star told US Vogue magazine: "[I like to] feel a little irresponsible and act like I'm 19.
"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.
"Or roll into a bar and get f**ked 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."
The singer also admitted that she prefers to live in a fantasy world, rather than conducting her life through "truth".
The eccentric dresser said: "I hate the truth so much that I would prefer a giant dose of bulls**t any day."
