I bet you didn’t know that Robbie is a ghost freak. In fact he’s obsessed with them. Recently he requested to be introduced to a ghost hunter.

While in L.A. he saw Gail Porter and Chris Parker – who were filming a show about spooky happenings – and dashed over to plead for an introduction to their ghost-hunter subject.
Robbie told them he’s a huge fan of the show, and started going on about ghosts. He even spoke about visiting the ‘Dead Famous’ set.

But this behavior is not something new, earlier this year Robbie sad he believes Britain will soon be invaded by aliens.Robbie is convinced the planet is about to be overrun by extra-terrestrials invaders and warned his fans to be prepared for a close encounter of the third kind. He told Britain’s Radio 2: "I’ve been dreaming every night about UFOs, every night. I can’t wait to go to sleep at night because those dreams have been so brilliant. "I think they are definitely on their way, seriously. Mark my words. From now until 2012 – watch out kids."

Me think this is another ScienTOMogy nut case.
