Mark Hoppus was asked by Maxim about his thoughts on Tom DeLonge's alien pursuit, to which he replied:
"I don't know [where his passion for aliens comes from], but he's always been really into aliens and conspiracy theories.
"It's always been something that's very important to him and he's always pursued. He does a lot of research and gathers a bunch of information, and he would talk about it all the time."
