London: Pop star Katy Perry says she is obsessed with aliens. The 'ET' hitmaker, whose divorce from Russell Brand will be finalised in July, says she wants to look beyond the Christian teachings imposed upon her by her pastor parents Keith and Mary Hudson during her childhood, a website reported.

"I'm fascinated by that kind of stuff because of how I grew up, where everything was so black and white. Now I'm seeing a lot more colour in the world and asking more questions. 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".
