Lady Gaga is one of the most visible celebrities in the world, but she says not everything she does is documented.

In the September issue of Vogue magazine, Gaga says she likes to "feel a little irresponsible and act like I'm nineteen." She goes on to admit she even manages to "roll into a bar" and dance topless or have sex on the beach without getting recognized.

The 26-year-old singer credits her friends for helping her not get caught by paparazzi.

The September issue of Vogue is its 120th anniversary issue and the magazine's largest yet.

It goes on sale Aug 21.
