Dappy would "knock out" an alien if he met one.

UFOs? No. I don't believe in ghosts, I don't believe in spirits, I don't believe in UFOs. If I see one I'll knock 'em out.

The 'No Regrets' singer doesn't believe extra-terrestrials exist but insists if he did ever have a close encounter of the third kind he wouldn't be scared to fight an alien.

When asked if he believes there are other species in the universe, he said: "UFOs? No. I don't believe in ghosts, I don't believe in spirits, I don't believe in UFOs. If I see one I'll knock 'em out."

Just as Dappy doesn't believe in Aliens, the 24-year-old rapper doesn't accept the numerous conspiracy theories that surround so many major global events.

When quizzed about conspiracy theories to mark the release of 'The Event' on DVD and Blu-ray, the N-Dubz star added: "You know the whole conspiracy thing, the world of Illuminati, Freemasons, listen, whether it's true they are not bothering us. You can just want to believe it and you'll start feeling paranoia and frustrated with your own self, 'Yeah what are they actually gonna do? They are going to put chips in my arm, or they are gonna do this or they are going to do that.' And you think to yourself as long as they don't bother me and they don't touch me and they don't physically harm me whoever these people are, Masons, the world of Illuminati, I don't believe it. As long as they don't touch us, we are fine - so forget about them."

'The Event' - which focused on a group of extraterrestrials who have been detained by the US government for 66 years since their ship crashed on Earth - is out now on DVD and Blu-ray courtesy of Universal Playback.
