Lady Gaga gives away her fake eyelashes after sex.
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."
