Katy Perry's first kiss with Russell Brand made her hop like a bunny. She told Glamour, 'When he was filming 'Get Him to the Greek' I did a cameo with him. My scene called for me to make out with him. And on the way down the stairs after the scene, I was hopping like a bunny. I hop like a bunny when I'm happy - I get a bit childlike'.
