Justin Bieber has received rave reviews from the Brazilian model who filmed him sleeping after they reportedly spent a steamy night together.

“Take it from me, he’s well endowed — and very good in bed,” Tatiana Neves Barbosa, 27, told  The Sun in a raunchy tell-all.

“It was one of the best moments in my life. It was marvelous and unforgettable,” Barbosa told the tabloid.

The model ended up at Bieber’s rented villa last week after a member of his entourage pulled the model aside and asked her to come to a private party where the 19-year-old’s very own music was blaring over the speakers.

Barbosa even asked Bieber to change the music after she arrived, but the the teen simply replied: “No, I don’t like other types of music.”

Bieber eventually asked everyone to leave the party and led the model to his room. She told The Sun she was so tired after their night together, she had to decline his invitation to come back the following afternoon.

“I didn’t — because I was exhausted,” she confessed.

Barbosa blames her friend for leaking the video she had sent just to prove that she was with Bieber.

“The video was just for her eyes only. I am really angry with her,” Barbosa said.
