F1 world champion Lewis Hamilton’s ex-girlfriend says he was obsessed with threesomes — and went crazy when someone used his toilet.

Glamour model Veronica Valle says the British athlete’s behaviour became increasingly bizarre, with sudden mood swings over seemingly trivial incidents.

Speaking exclusively to The Sun, Veronica said the racing driver was charming but had a “dark side”.

She continued: “Lewis is a very strange character.

“He’s Jekyll and Hyde. He can change his mood very quickly and sometimes it’s just because someone uses the wrong toilet.”

Veronica said Lewis, who was on the Caribbean island with a group of other women, was initially “sweet” to her.

But she soon realised how quickly he could lose his temper – after he flew her away on his private jet a few weeks later.

She said: “We were flying to New York and Lewis went berserk when he discovered the pilot had pooped in the toilet.

“He was going to fire the pilot! He said, ‘Everyone knows they shouldn’t disrespect my plane’. He was really angry.”

Veronica herself then fell foul of Lewis’ strange toilet rules — and was confronted by him as she emerged from the loo at one of his properties in the South of France.

She recalled: “A few months later, at his house in Monaco, I ended up having to use the toilet that was next to the kitchen to do a number two.

“He saw me come out and said, ‘Why did you take so long?’

“I told him I was pooping. You could tell he was so upset.

“I felt like he was going to scream at me, but in the end he just said, ‘You know you’re not allowed to use that!’

“He told me to use the one in the living room. It was weird.”

Veronica insists that even eating ice cream the wrong way can cause the world champion to lose control.

“One day, I was about to eat ice cream and he screamed at me,” she said.

“He took the spoon and said, ‘You have to do it like this’ – and he scraped a little layer off the top.”

Veronica said: “I didn’t have my bag for four days, but he didn’t even ask me if I needed anything or offer to buy me clothes.

“I didn’t even have a toothbrush or a spare pair of underwear. I had to wear the same clothes for four days straight!

“Then we had to go to London and I went and bought some clothes for myself.”

“Somebody later  said something about having a threesome with Karrueche Tran. I said no – I wouldn’t do that.”

On another  trip to Barbados, the Formula One ace joked about Veronica joining him for a tryst  with another woman.

She said:    “I was so embarrassed – nothing happened. But I think he was just joking about threesomes. As far as I’m aware he never actually had any.”

I saw him for the last time in Barbados after a long break. I said: “I went to a party with him and I went to ask if he was okay – but he just swore at me.

“He told me to ‘get out of there’ and that ‘it was none of my business’.

“I don’t understand why I was invited on that trip to be treated like that. His friends say that when Lewis drinks, he loses his temper. He doesn’t act like that.

“After just one drink, he changes and becomes very rude.”

However, she said she only saw him when he wasn’t racing, adding: “He always seemed very focused on his career.”

“He can be charming, but he has an ugly side.”

Veronica said she changed her phone number after realising Lewis only wanted sex with her.

She added: “I really liked him but after a while I felt like he just wanted to have sex and then leave me.

“I don’t know where that came from. I was so confused. He was so mean to me. He wasn’t the sweet guy I first met in Barbados.

“I felt like he was just using me for sex. It felt really bad.”
