Peter Andre has struck up a friendship with fellow singer Robbie Williams over their shared fascination in extraterrestrials.
The Mysterious Girl hitmaker has been sending emails to the Take That singer, who shares his enthusiasm for aliens.
He tells Britian's Daily Star, "I have seen Ufos - seriously, I'm not joking. I'm so intrigued by the idea of life on other planets. I feel really strongly about what I've seen.
"I've been having email conversations with Robbie Williams. We send each other pictures of our findings and chat about aliens and the possibilities. It sounds really geeky, doesn't it?
"I don't get to see him much, but we both love chatting about Ufos and emailing pictures of puzzling looking lights."
Andre reveals he has even travelled to Las Vegas to visit the American military base Area 51, which has become a hotspot for Ufo sightings.
He says, "It was amazing. What we saw was freaky whether you believe it or not. It was the most eerie thing ever. I 100 per cent believe aliens exist."
