Robin Williams is being haunted by the ghost of king Henry VIII's last wife Catherine Parr, while he was sharing with her girlfriend Ayda the seven million pound mansion of Catherine Parr, the infamous British monarch's sixth and final spouse in Wiltshire, South West England. He felt the presence of her spirit there in the mansion.
He explained: "I think there are ghosts. I haven't seen or heard anything. I've definitely felt something but it's not scary. I'm very, very pleased to say.
"It's Catherine's Parr's old house. In fact, we're actually not in the old house, we're in her barn."
Robbie and Ayda moved from Los Angeles to Britain earlier this year to prepare for his musical comeback.
Robbie said: "I can't even believe that a 35-year old me has bought a 500-year-old place. Because at 26 or 27 there's no way that I would have chosen to be there or go anywhere near it.
"But it's lovely and the people have been great with us."
It's not the first time Robbie's house has been linked to paranormal activity.
The star reportedly purchased the property because it is crossed with 'ley lines' - invisible energy routes believed to attract aliens.
Robbie is "obsessed" with extra-terrestrials, and claims to have seen three UFOs during his lifetime.
