IF we had to pick a celeb to like this stuff, she'd deffo be the one.

Katy Perry says she's obsessed with aliens, and that they won't kill her because she once wrote a song called E.T.

The Part Of Me singer said: "I'm fascinated by that kind of stuff because of how I grew up, where everything was so black and white."

Russell Brand's ex wants to look beyond the Christian teachings imposed upon her by her pastor parents Keith and Mary.

Katy's interest apparently started when she watched a US show called 'Ancient Aliens', and she loved it so much that she's trying to get everyone she knows to watch it.

She said: "I sent out a Christmas gift basket to people filled with my favourite things and the first season of 'Ancient Aliens' was one of the things I included."

"It's so good. I made everyone on my tour watch it. I'm just obsessed," she added.

"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 E.T.," she added.

She's thought about this A LOT, hasn't she.
