Leading ufologist and documentary maker Mark Christopher Lee believes Robbie's encounters and said there seemed to be a mysterious link between musicians and UFO sightings.
Robbie's extra-terrestrial experiences span three decades and Mark said he believes they keep happening because he has allowed himself to be open to contact.
But since becoming a dad to four kids with wife Ayda Field - Theodora or 'Teddy', 12, Charlie, 10, Coco, six, and four-year-old Beau - Robbie says his close encounters have completely stopped.
I had a house in Wiltshire, the grounds and the house were a thousand years old and you would think that there I would be inundated with spectres or doors slamming.
He claimed the unidentified flying object was so close he could have hit it with "a tennis ball" - and said he wasn't under the influence of any substances at the time.
