: This is Tati Neves, the girl who made headlines around the world after filming Justin Bieber sleeping at his rented mansion in Brazil, leading to stories that she had sex with the pop star. The curvy brunette showed all her class as she arrived at a party for men's magazine Sexy in Sao Paulo in a tiny dress - that frequently gave party goers an eyeful of her white underwear. Clearly happy to be linked to Bieber, she however said she could not reveal exactly what happened. "At the moment I can't say anything yet," she said. The girl has been surrounded by rumours first that she was a prostitute then that she was a transexual. It has emerged she is a wannabe model who tried to be the representative of Flamengo football club in a national league beauty pageant.
