A message therapist who treated Prince Andrew in his bedroom has claimed that the disgraced royal has been her creepiest client till date, saying that he was a “constant sex pest.”

Massage therapist Emma Gruenbaum got introduced to Prince Andrew after treating his ex-wife Sarah Ferguson in early 2005. She was then vetted by Palace staff and visited Andrew six times in the same year.

In an interview with The Sun, Gruenbaum recounted her time with the disgraced royal, saying, “I had a lot of high-profile clients and often visited their homes. But Andrew was very different. He was a constant sex pest right from the start.”

Gruenbaum’s first official encounter with the Duke of York was set up by his personal secretary. Gruenbaum was invited to the Royal Lodge in Windsor Great Park on a Sunday evening for her services. Despite the unusual request, she agreed.

“I was led through the house by a member of staff. I followed him up a couple of flights of stairs and ended up in the bedroom, a very impressive master suite,” Gruenbaum told The Sun, recounting her experience that day.

“I said, ‘Oh I’m not really comfortable doing this in his bedroom.’ I looked at the massage table and I said, ‘And that is much too high.’ It was up to my hips so I’d be kind of there massaging at boob level, which is something I obviously didn’t want. So I said, ‘Can we move it out of the bedroom? I am not comfortable,” the 50-year-old told the publication.

“But I was told it wasn’t an option, this was the way the Duke liked it…I was told not to make a fuss. I didn’t know what else to say and the staff member left,” she added.

Gruenbaum went about setting up her massage table in the bedroom and it was then that the Prince made his appearance.

“I heard a voice, ‘Hey nice a****. Do you take it up the a***?’ I stood up quickly and turned around. I was up against the massage table and he was up against me, eyeball to eyeball. Almost touching, he was really close,” she told The Sun about the Prince’s entrance.

“And I went, ‘None of your f***ing business.’ And he just looked at me in sort of a dead stare and said, ‘You can’t talk to me like that.’ I said, ‘Well you can’t speak to me like that.’ There was then a momentary silence where I was sort of staring at him and I tried to step sideways and get away from being up against the table. It was just so tense, it was really weird,” Gruenbaum added.

“But I have had stupid comments over the years and I just said, ‘Look are you going to behave? Get your robe off and lie down and let me do my work. Or am I leaving?’ And he said, ‘No, I think we’re going to get on just fine’,” the therapist said, explaining her arrangement with the disgraced prince.

However, her sessions with Andrew always left her uncomfortable, and the 50-year-old told The Sun, “I always looked away as he got on the table and made sure there was a towel covering his modesty, but he was always naked under the towel. We started the massage. But all the way through he was talking about anal sex and making anal sex jokes. He asked when I had last had sex. It went on and on.”

“He asked me to watch a movie a couple of times. Once he said he wanted to make me a cup of tea and led me off somewhere as I was leaving. We ended up in the kitchen and he said he didn’t even know where the kettle was. I just wanted to leave. I said firmly, ‘Look where is the way out?’ And I left,” she said of the Duke’s advances.

Gruenbaum stopped getting calls from the Duke’s office after a couple of months: “I think it is because he wanted more and he was clearly not going to get anywhere,” the therapist told The Sun.

The 50-year-old further added, “I just really want to add my voice and my experience to help, if it does help at all, to add context on what sort of character he is and how he treated me. And if that helps Virginia [Giuffre] then fantastic.”

Prince Andrew stands accused of child sexual abuse by Virginia Giuffre, who claims that she was trafficked by convicted sex offender Jeffrey Epstein at the age of 17 to have sex with the Duke of York. Andrew, however, denies his involvement, but is facing a trial in New York later this year.
