The 23-year-old 'Someone Like You' singer reportedly believes her 10-bedroom home is Sussex, England, is being staked out by Ghosts, and has invited super-natural enthusiast Robbie and his wife Ayda Field to come and experience the spooky goings-on.
A source said: ''Adele's often said she hates staying at Home Alone in the mansion because she's sure it's haunted and she gets spooked.
''She knows Robbie and Ayda are fascinated by the supernatural and has offered to have them to stay for a haunted weekend any time they like.
''Adele thinks they are both fantastic and would love to spend some time sharing ghost stories and witnessing paranormal activity.''
The Grammy Award-winning star left London and moved to the £7million house a few months ago after undergoing surgery on her vocal chords. It is thought doctors advised her the clean, country air could aid her recovery.
A source told the Daily Mirror newspaper: ''Adele is a London girl through and through, but she's never been particularly into the showbiz circuit so when it was suggested she move out of the city, she agreed immediately.
''The idea is for her to live in the countryside, away from the capital's smog and pollution.''
