The `Tik Tok` singer has recently taken up painting in order to relax while on tour and she has now taken a new approach by using herself in her work. She said: "I have recently taken up painting as a way of killing time on tour. "I got a big canvas, threw some paints down and then stripped off and rolled around on it. "It`s very liberating. And very, very messy." The 24-year-old singer also revealed she recently had a bizarre dream about "making out" with Lady Gaga. She recalled to Q magazine: "Last week I dreamt I was a pre-school kid making out with Lady Gaga. That woke me up. "I have pretty wild dreams as it is, but this was so vivid. Will I tell her about it in real life? No way. I haven`t really met her properly but that`s not really the way to break the ice."
