Basement Jaxx star Felix Buxton has written a song about aliens after catching a glimpse of what appeared to be a Ufo outside the band's London headquarters.

The electro musician has revealed he saw what he believes was a flying saucer out of the window of the group's studio near King's Cross in the British capital.

Buxton was spooked by the encounter and went on to write a new song, titled We Are Not Alone, about the experience.

He tells Britain's The New Review magazine, "(I saw) something very still and glinting in the sky, like light reflecting off a car... it looked like a flying saucer, basically."

He even mentioned the incident during a talk he gave to students at England's Oxford University and was glad they didn't make fun of his encounter, adding, "The students were cool about it - whereas people of my generation tend to get angry when I tell them I saw something I don't understand. It shows how closed-minded people are, generally."
