He shared a bed with Michael Jackson and was nicknamed “Rubba Rubba” boy by the superstar.

When he was a baby-faced 14-year-old Michael Jacobs-hagen joined Jackson on a string of tours – smiling for the world’s media as he posed happily with the singer.

But today he reveals for the first time the full, horrific details of his bizarre relationship with the star who took him into his bed.

And he admits that only now, as the father of a three-year-old himself, does he realise the twisted and serious nature of the abuse he suffered at the Jackson’s hands.

Speaking exclusively to the Sunday Mirror, Michael, 35, said: “He overstepped the mark with me and with other children.

“I’m almost the same age now Michael was when he met me.

“If I was to share a bed with a child, this would not be right. It is not normal and it’s not right.

“He was always asking me to sleep in his bed. I would say, ‘No Michael, I can sleep in my own suite’, but he was saying ‘Please, please... for Michael Jackson’.

“Since I had a son, it made me look at everything in a different way and I realise now how wrong it was. Becoming a father changed my feelings.”

Michael also reveals the star:

Touched him inappropriately after cuddling up to him in bed And it was always worse if the star had taken medication.

Stripped naked as they shared a Jacuzzi.

Gave him a book “full of photos of naked boys”.

Bought his silence with gifts – and even gave his mum a Cartier watch.

Michael is now a public ­relations manager and lives in Munich, Germany, where he was famously snapped at a hotel window with Jackson and pictured in newspapers round the world as the boy in the back-to-front baseball cap.

The King of Pop – in his trademark face mask – was 38 and touring Europe promoting the HIStory greatest hits album.

Michael spent three weeks with the singer in the hotel suite.

He said: “When I got back to school, pictures had been in all the media. Other kids would say, ‘You make sex with Michael Jackson’ and ‘You’re gay’.

“It affected me psychologically, but I never told Michael. It made me feel shame. Teachers warned my mother about allegations about Michael, but she said it was my decision if I wanted to keep seeing him.”

Michael had been thrilled to meet Jackson during an earlier visit to Disneyland Paris – after his mum asked an aide if her lad could be introduced to the star.

He recalled: “Suddenly I was being picked up and taken to another hotel. When I went into his suite and Michael Jackson was there waiting for me, I just thought ‘Wow’. I was a huge fan.

“He gave me a hug and said in German ‘I love you’. We spent the day playing games like hide and seek and on his PlayStation.

“After that he kept phoning every day asking ‘Do you want to come again?’ and we spent the whole holiday together.

“Michael invited us to other concerts, including the HIStory Tour, when I was 14. I travelled with him to other countries.

"When I slept in his bed, we wore just boxer shorts and he would put his arm around me and push his body to my body, like you would with a girlfriend.

“He would put our bodies on each other and kiss me on the head and cheek. I woke many times and his hands were on me... one hand on the top of my legs and one hand around me.

“When he was high on his medication he would get closer in the same way as when a man gets drunk. It disinhibited him.

“He’d pull me closer and be grabbing me more and kissing me more on the head and on the cheek, He would also stroke my hair.

"I didn’t feel comfortable with it, but I thought ‘I can’t say No’. When you’re 14 and you’re there with the biggest megastar in the world, you say ‘okay’.

“He never carried out an explicit sexual act on me, but there were sexual intentions.

“He must have been getting something out of it sexually. I feel now like he was testing me, seeing how far he could go.”

The star was infatuated with Michael and sent notes saying he “truly missed him” – as well as instructions on hotel meets.

Michael also told how Jackson gave him a copy of The Boy: A Photographic Essay, containing naked snaps of young lads.

He said: “I found it strange. He said ‘This is one of my favourite books’ and he wrote personal notes inside. In one he called me ‘his special friend’ and his ‘rubba rubba friend’ because of what used to happen in the bed.”

Years later, another copy of the book was found in Jackson’s bedroom at his Neverland ranch in California after he was arrested on suspicion of abuse.

Jackson’s 14-week trial was held in Santa Maria, California, in 2005. He was cleared of 10 charges – even though alleged victim Gavin Arvizo told the trial he had slept in the same bed as the star as a 13-year-old.

Michael, meanwhile, told the Mirror about the time Jackson stripped off in front of him in a hotel hot tub. It was 1998 – three years after they met.

He said: “We were in the Jacuzzi inside Michael’s bathroom. He took his swim shorts off and said ‘If you want, you can take yours off as well’.

“I told him ‘No, I don’t do that. I don’t feel comfortable being naked. I was 14, but I always looked younger.”

The teenager told no one – not even his mum, who had split from his dad – about Jacko’s behaviour. But then the star had groomed him to remain silent and even bribed his mum.

Michael went on: “He would buy expensive things.

“He bought my mother a Cartier watch. We would go to toy shops or the Disney store and buy whatever I wanted.

"And he would drink wine and offer it to me. But I always said no. He called white wine ‘Jesus juice’ and red wine ‘Jesus blood’.”

Michael only came clean with his mum after Jackson died from a prescription overdose in 2009.

He said: “She said that she gave him too much trust. She was very upset. All the time I was with him he needed psychological help. He was not okay.”

Michael now has a son aged three but is estranged from the tot’s mum.

He last saw Jackson in Las Vegas two months before his death at the age of 50.

He added: “When I became a man he did not have so much interest in me. When I went to visit the last time he didn’t ask me to sleep with him. I had to sleep on the couch.

“His fans won’t like me saying these things. They treat him like a God. But the truth is the truth.”
