Justin Bieber

Justin Bieber reportedly partied until 9 a.m. in Rio de Janeiro with a group of girls he met at a Brazilian nightclub.

The 19-year-old singer took several ladies back to a private mansion on Saturday.

According to UK newspaper The Mirror, the lucky ladies were 'fed chicken nuggets, chocolate, snacks'. Guests’ phones were confiscated and were forced to sign a non-disclosure agreement before they were allowed in.

Student Marina Binimeliz shared what it was like hanging out with the Baby hitmaker that night.

'We weren't told to go exactly,' she said. 'Justin just said I'm tired. I think I need to go to sleep. He came to me, put his arm around my waist, squeezed me and kissed me on both cheeks. He told me I was very cute.' 'At one stage he got a little crazy and jumped on to a wall and yelled, 'I'm the king of the world,'' she alleged.

Marina also said the home smelled of marijuana, although she did not reveal if she saw the drug being used.

At the end of the evening, she said Justin's security team prevented her from taking photographic evidence of her agreement not to talk.

'We all had to sign contracts saying we wouldn't take any photographs and if we did we agreed not to publish them. I was only given my phone back when I left,' she said.

'I tried to take a picture of the contract but they whipped the phone out of my hand before I could do so.'
