Beauty blogger Jayde, 19, was first contacted by Bieber in April through her popular Instagram page.
She said: “I saw there was a tick by his name showing it’s an official account. I thought, ‘sh*t, Justin Bieber just messaged me’.
“I have no idea how he came to look at my page. I was at a family party in London at the time and I was like, ‘What?’. I said to my friend, ‘Justin Bieber just messaged me – look’.”
After exchanging messages the Baby singer then asked for her number and they began swapping texts regularly.
Jayde, who has been video blogging since she was 13 and has 200,000 Instagram followers, said: “He would just be saying normal things like, ‘Hey, how was your day’, and I was asking him the same.”
After four weeks of messages, Jayde let Bieber know she was on holiday in Miami and he suggested she fly to Los Angeles.
She said: “When I arrived he was sitting in the garden playing guitar – he just looked up and said, ‘Hey, how was your flight?’”
Sitting by the hot tub in his garden the pair were joined by security guards as Bieber serenaded Jayde with a version of Justin Timberlake’s Cry Me A River.
She said: “His voice is a dream. When he started singing I was like, ‘Oh Jesus…’ “
For the next six days Jayde stayed at Justin’s house and got a glimpse of the star’s life away from the cameras.
“He’s a real laugh,” she said. “He has a robot in the living room and at least three electric scooters that came everywhere with us.”
They went to Macy’s department store in LA’s Beverly Center and he insisted on buying her £70-worth of Anastasia Beverly Hills make-up.
She said: “We went to the gym a lot. That’s where we were papped, the pictures went all over the world.”
And she revealed the singer only wanted to work out to his own songs – handing gym bosses a personal playlist.
Jayde said: “It was quite funny, only one other person was in the gym but he walked in and asked for the music to be changed to his playlist straight away – he takes his own music very seriously.
“I was just watching. I didn’t do any exercise. He told me he’s trying to build his chest and arms.”
Bieber, who dated actress Selena Gomez, 23, for four years, took Jayde to his regular hangout, LA’s Mondrian hotel, and treated her to one of his favourite meals, salmon and mashed potato.
During her stay the pair also went hiking at nearby Runyon Canyon, and visited an art festival.
Jayde said: “Another time he got up and went to church. It was clear God is a big part of his life – he brought God up quite a lot, he’d say things like, ‘Do you know God loves you?’
“We actually prayed together – once it was with some of his friends in his car before going to the recording studio.”
After a week with one of the world’s most famous pop stars, Jayde began to get attention from the millions of Beliebers who track their idol’s every move. But the reaction was far from positive.
She said: “I had thousands of messages from people calling me racist things like ‘monkey’. It’s annoying his fans can’t respect he can hang out with who he likes.
“Justin told me he blocks social media when bad things are being said about him.”
Many messages were in response to rumours Jayde was sleeping with Bieber, but she insisted: “We’re just friends.
Honestly, most of the time we spent chatting. Nothing more. He’d tell me, ‘You don’t need make-up. You look pretty naturally.’ And he loved my British accent. I definitely fancied him too.
He’s messaged to ask how my flight was – it wasn’t a ‘bye forever’, it felt like ‘bye for now’ – if he came to London I’d see him.
“I haven’t heard him say he’s coming, but never say never.”
