More details about Tatiana Neves Barbosa, the mystery woman who revealed she spent the night with Justin Bieber in Brazil, have surfaced since her video leak last week.

Barbosa, who filmed a video of herself with the sleeping teen pop singer, is reportedly "very upset" because she did not intend for her personal video to go viral.

A source told E! News that Barbosa "sent the video to a friend and did not realize it would be put online."

"She does not know what to do," added the insider about the clip that has garnered over 34 million views on Youtube.

Barbosa spilled the beans about her secret tryst with Bieber in a recent interview. The 26-year-old model, bodybuilder and part-time actress who is rumored to be an escort, told Global TV's Fantastico that she spontaneously filmed him for a friend.

"I was sleeping, and woke up," she explained in Portuguese, her native language. "He was sleeping and I was speaking with a girlfriend."

In the short video she released, Barbosa is looking at the camera after Bieber is seen sleeping. She then blows a kiss to the 19-year-old pop singer.

Egotastic reported Nov. 7 that Barbosa is an escort who won the Miss Bikini Wellness contest in 2012. The website found nude images of her featured in a men's magazine called Private where she advertised her services. View the NSFW graphic images of Barbosa here. 

Bieber's camp, however, disputed the reports that she is an escort and that the pop singer paid for an intimate romp with her. An insider told TMZ he rented a house just outside of Rio and had a party there. When the 19-year-old fell asleep on the couch one of his invited guests filmed him.

The "Biebs" is reportedly "creeped" out by the video and is "upset he has to deny hooker claims" according to the source.
