Hugh Grant? He emits a negative frequency of cynical energy: Lady ghostbuster who came to exorcise his house says the actor's attitude was to blame for her failure 

His bumbling, very British romcom persona is familiar to millions.

But clearly Hugh Grant decided it was time to mix in a little horror film edginess and New Age wackiness.

His bizarre revelation that he had resorted to using a ‘sage-burning, drum-banging’ exorcist – when one of his four children saw a ghostly apparition – backfired spectacularly, however.

Hugh Grant revealed he had resorted to using a ‘sage-burning, drum-banging’ exorcist when one of his four children saw a ghostly apparition

It led to claims that the 55-year-old actor ‘emits a frequency of cynicism’, mixes up his facts and is filled with negativity.

Speaking on James Corden’s Late Late Show in the US on Thursday night, Grant said he had summoned the help of a ghostbuster called Wendy Mandy.

‘I’m a rational person, well educated, not an idiot and I find myself ringing a ghostbuster.

‘It’s so shaming,’ he said, adding that he should have known better than to have hired Miss Mandy.

He claimed the exorcist visited twice a week and played songs and waved sticks around his house in London. When she entered his son’s room ‘her sticks went completely wild’ and she said the presence of the ghost was ‘so strong in here I think I might throw up’.

Grant added: ‘She burnt about 7lb of sage then banged a little drum and played an instrument and said all the spirits are gone.’

Ghostbuster Wendy Mandy blamed Grant’s ‘cynical’ attitude for her failure to get rid of the poltergeist

He described the whole experience as ‘b******s’, especially as his son claimed to have seen the apparition – the ghost of a little boy – again the following day.

But yesterday the ghostbuster hit back and blamed Grant’s ‘cynical’ attitude for her failure to get rid of the poltergeist. Miss Mandy, who calls herself the ‘genuine article’, claims her methods are based on ‘quantum physics’ which she has studied for several years.

She said: ‘Hugh Grant is a very cynical person. When you’re in the presence of a cynical person it’s quite difficult; they’re emitting a frequency of cynicism.’

‘I see a lot of celebrities and lots of famous people but I keep schtum. Sometimes you have to visit a few times. I went once. I wouldn’t go back.’

Of Grant’s claims about her methods, she said: ‘It was a while ago that I went, maybe last year. I use a Peruvian rattle, not sticks. It wasn’t exactly a song – I used a Tibetan singing bowl to change the sound frequency. I did not use sage. He’s probably mixing up lots of healers. This is science – quantum physics.

‘There are different frequencies that exist and if someone has some kind of energetic disturbance a child or very sensitive person may experience that. You have to settle the frequency in some areas.

‘Everybody knows that when you walk into a house it feels good or it doesn’t feel good. Children particularly, dogs, cats, horses and sensitive people can really feel that.’

Miss Mandy said she has been performing similar services for 37 years, as well as acupuncture and reiki, and boasts several celebrity clients, but it was Grant’s disbelief and emission of the ‘frequency of cynicism’ that led to the ghost returning. ‘I would have had to make several visits,’ she said.

‘I did what I could. When you’re dealing with frequency you’re dealing with something in the intellectual left brain. Science is proving that plants have their own language, animals have their own language – it’s a frequency language, it’s not upper-class English Hugh Grant language.

‘I only went to his house because I liked the person who recommended me a lot. And because it was a small child and I wanted to help a small child.

‘Otherwise Hugh Grant would not be one of my clients. I don’t treat cynical people – there’s no point. It [frequency] is actually quite a complicated subject, I can tell you I’ve studied feng shui for ten years amongst other things. People can trivialise it.

‘The rattle and the bowl are ancient traditions that I’ve learnt from travelling around the world. There is no course where you can learn what I’ve learnt. I’m the genuine article.’

Grant did not reveal which of his two sons kept claiming to see a ghost. But the Notting Hill and About A Boy star told Corden: ‘From a very early age whenever you stroked his head he’d stare into a corner of the room, then other kids would come round and say “Who’s that little boy over there?” – it was completely out of control.’

Grant has a four-year-old daughter, Tabitha, from what his publicist called a ‘fleeting affair’ with Tinglan Hong, a Chinese-born receptionist. He also has a three-year-old son, Felix, with Miss Hong, the result of a subsequent reunion.

Grant has two children with Swedish TV producer Anna Eberstein – a son John Mungo, three, and a daughter born in December 2015.

Both women were pregnant at the same time with his sons.
