Robbie Williams wishes he had kept quiet about his love for aliens-because now the media constantly asks him about his unusual hobby.

The 35-year-old became a recluse in the mid 2000s, abandoning Britain and his career to chase a lifelong interest in the paranormal in the US.

However, the Angels hitmaker regrets opening up about his fascination with extraterrestrials, as he's always bombarded with questions about them.

"It's my own fault but it (the most annoying question) has to be anything to do with aliens and UFOs. It's not the question but it's the intent the person asking it always has," the Daily Express quoted him as saying.

"You can see in their eyes - they look at you like, 'Have you gone mad or not?'. You feel as though you have to explain yourself and your level of sanity," he added.
