Tom DeLonge
The Blink-182 guitarist is adamant that aliens exist, so much so that he has become one of the leading public voices on the web.
In 2015, Delonge said: "I have sources from the government. I’ve had my phone tapped,” alluding to officials reaching out to him about UFOs.
The musician has even formed the company 'To The Stars Academy of Arts and Science' which specialises in researching alien life.
Unfortunately, DeLonge won't elaborate on his extra-terrestrial experiences since he is "bound by my nondisclosure agreement".
