The 'Bad Romance' hitmaker thinks she is being followed everywhere she tours across the world by the spectre, who has 'terrified' her with his constant presence.

A member of her touring crew told the Daily Star newspaper: 'She's been telling us all for months that she has a male spirit called Ryan who travels the world with her.

'She's pretty terrified by this spirit, but more than anything he's annoying her as he won't leave her alone.

'He's hasn't been doing anything too violent or scary but she's freaked out by his presence. She's a very spiritual person and in tune with the spiritual world but this is a step too far, even for her.'

Although little is known about Ryan the ghost, or why he has chosen to haunt Gaga, she has held a seance while in Ireland for her 'Monster Ball Tour' over the weekend, in an attempt to get through and see him off.

The source added: 'She contacted a spirit medium and organised a seance so she could communicate with him and tell him to go away.

'She gathered all her friends over the weekend in Belfast, Ireland, and held the seance to find out what he wants. She's convinced she picked this up as a bad omen.

'Although most of her friends were sceptical they agreed to take part.'

It has previously been revealed that Gaga, 24, has spent thousands of dollars on ghostbusters and splashed out $47,000 on state of the art Electro Magnetic Field meters to detect spectres.

A source previously revealed: '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."
