The ‘Poker Face’ beauty - who is known for her outrageous and skimpy outfits
- peels off her long lashes and leaves them on her lover’s bed after they’ve
spent the night together.

She said: “Whenever I have a lover I leave them in their apartment on the
pillow. Kind of like a keepsake.”

The 23-year-old star - who used to work as a burlesque dancer - says her
raunchy streak stems from an incident in a New York bar before she was
famous.

She explained to Britain’s Independent magazine: “There was this one night
where I had had a couple of drinks. I had new material and I had on this
amazing outfit. I didn’t want to start singing while they were talking, so I
got undressed. There I was sitting at the piano in my underwear. So they
shut up.

“That’s when I made a real decision about the kind of pop artist that I
wanted to be. Because it was a performance art moment there and then.”
