Looks like Travis Barker has another musical associate who believes in extraterrestrial existence. Machine Gun Kelly was a guest on The Late Late Show With James Corden (with Barker joining him for the musical performance) and he opened up about his experiences with potential alien life.
Corden references "Concert for Aliens" that Kelly and Barker would perform before asking of the musician's beliefs. Kelly confessed, "Homie, I saw life on this planet that was from another planet two nights ago, over a lake in Thousand Oaks. A red orb came out of nowhere, went and disappeared again."
