Will I Am has done some crazy stuff in his time but our favourite has to be his latest idea. Today, he is going to debut his new single on Mars – yes, the planet Mars. We’re not sure who he is expecting to listen to it – aliens maybe? Will is friends with the important people at NASA and they are going to play his single Reach for the Stars through the speakers of the curiosity robot which landed there a few weeks ago. There will actually be some human beings listening to the track – students at a laboratory in California will also be able to hear the whole thing. Will has never hidden his love of the solar system and even when the robot landed recently, he tweeted excitedly and said: "We did it!!! We landed on Mars... we did it humans ... humans landed Curiosity on Mars." And back on earth. Will I Am has just recently signed up to appear again as a judge on The Voice in the UK. Let’s hope he sends some of the awful contestants out into space!
