Justin Bieber's Brazilian fling thinks he's one of the ''best'' men she's ever had sex with.

The 'Boyfriend' hitmaker hit the headlines this month when footage emerged of him asleep after a night of passion with 27-year-old Tati Neves Barbosa - whom Justin invited back to his rented villa in Rio de Janeiro along with a group of women.

She told AKM-GSI photo and media agency: ''There was a lot of exchange of affection. [He] was one of the best I've ever had. He was the way a man has to be in bed.''

The 27-year-old - who has a five-year-old daughter with her estranged husband - claims Justin, 19, invited her and a group of other beauties to his Rio villa, but only had eyes for her.

Meanwhile, the brunette minx, who has denied she works as a prostitute, is adamant she didn't post the now infamous clip of herself and Justin on the internet, saying she filmed the video to prove to a friend she was indeed with the pop star.

She added: ''I didn't want the video leaked but now there is not much I can do. I filmed like any fan would. He is a star. He is beautiful.''
