Justin Bieber seems to be having fun while touring South America.

While performing in Rio de Janeiro, Brazil, the 19-year-old star allegedly spend the night with a Brazilian girl. As proof of their encounter, she posted a video on YouTube where Bieber can be seen sleeping in a hotel room.

Now, the girl, named Tatiana Neves Barbosa, has become a sensation in her home country. According to Fox News Latino, she was interviewed by Globo TV's "Fantastico" where, for the very first time, she talked about the night she spent with the "All Bad" singer.

Neves was asked about what she and Bieber did during their time together. "What do you think, if I was sleeping in the bedroom, just me and him?" the 27-year-old fan teased.

In the 15-second video, which went viral within minutes, Neves, also known as "Tati," can be seen blowing a goodbye kiss to Bieber, while he sleeps behind her.

Although she wasn't clear on whether they slept together or not, during an interview with British tabloid "The Sun", Barbosa gave further details on the night she spent with the teen idol. "Take it from me, he's well endowed - and very good in bed," said the Brazilian beauty, according to Us Weekly. "A man must know what do to make me happy - Justin did all that and more."

Neves claimed Bieber invited her to a party in the house he rented after he was asked to leave his hotel in Rio. During the interview with "Fantastico," she was asked if she'd seen other girls in the property. "No. I'd already gone into the bedroom with him," she replied, and added Bieber invited her to his bed once the party was over.

"It was one of the best moments in my life. It was marvelous and unforgettable," said Neves, as quoted in the Sun. "He has quite a fit body and he looked great naked." She told "Fantastico" she filmed Bieber the morning. "I was sleeping, and woke up," she said. "He was sleeping and I was speaking with a girlfriend."
