Lady Gaga reportedly spends thousands of pounds on ghostbusters to check every hotel and venue she is due to visit before she agrees to go.
The eccentric singer is terrified of evil spirits and reportedly has every hotel and tour venue scanned by A Team of paranormal investigators before she will agree to stay there, according to Britain's Grazia magazine.
The 24-year-old pop star - who has previously said she believes she is the reincarnated spirit of her dead aunt - has also allegedly splashed out £30,000 on state of the art Electro Magnetic Field meters to detect spectres.
A source said: "She believes in paranormal activity and won't take any risks when she is on the road. It's important to her to be safe from spirits."
Ghost-hunting equipment is not Gaga's only extravagant purchase.
The 'Alejandro' singer - who has reportedly lost $4 million on her sold out 'Monster Ball Tour' - spent £40,000 to hire a NASA trained chemist.
The flamboyant beauty - who is well known for her love of tea - splashed out the huge sum in order to discover a non-hot substance that would let steam out from a teacup-shaped dress.
Gaga has also spent £500,000 on private jets to transport her set equipment and wardrobe on the 'Monster Ball Tour', £15,000 on hand crafted lace from Eastern Europe and £52,000 on a bath tub for her performance on UK TV talent show 'The X Factor' last year.
She is reportedly eyeing up a British castle for her next purchase.
