Robbie Williams has struck up an unlikely friendship with former X Factor contestant Johnny Robinson.
According to The Sun, the pair have been hanging out at the X Factor results show every weekend discussing the subject.
A show source told the Daily Mirror: 'They got talking about aliens and UFOs and it was suddenly like they were old friends.
'They had a real connection and both believe in the paranormal so everyone else just left them to it.
'They were in their own little world talking about aliens and extra-terrestrial things.'
Robbie Williams is known for his interest in extra-terrestrial activity. In 2008 the singer even threatened to give up his music career to become a 'full-time ufologist.'
