Katy Perry obsessed with aliens

So I'm very into things that are above and beyond me and were before me and will be after me," she said.

The 27-year-old beauty is confident that aliens will one day visit Earth, but she hopes they won't want to conduct experiments on her because she previously wrote a song about them. "I do hope that when the aliens come, they'll recognise me. I'll be like, 'Please don't kill me, I wrote a song called ET".
