Lady Gaga spends thousands of dollars on ghostbusters.

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 $47,000 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 $63,000 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 $790,000 on private jets to transport her set equipment and wardrobe on the 'Monster Ball Tour,' $24,000 on hand crafted lace from Eastern Europe and $82,000 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.
