Brazilian beauty films Justin Bieber sound asleep after their fling

Justin Bieber is "very good" in bed, according to his Brazilian fling.

The 'Boyfriend' hitmaker made the headlines last week when footage emerged of him sound asleep after a night of passion with 27-year-old Tati Neves - whom Justin invited back to his rented villa in Rio de Janeiro along with a group of women - and the mother-of-one has boasted about his sexual prowess.

She gushed: "Take it from me, he's well endowed ... and very good in bed.

"A man must know what to do to make me happy. Justin did all that and more.

"It was one of the best moments in my life. It was marvellous and unforgettable."

Tati - who has a five-year-old daughter with her estranged husband - claims Justin, 19, invited her and lots of other beauties to his Rio villa, but ultimately had eyes only for her and the pair soon escaped to the bedroom.

The Brazilian beauty claims the 'Baby' star insisted on playing his own music while they had sex and he even begged her to come back for more after she had left.

Tati claims: "He has quite a fit body and he looked great naked. I didn't [go back] because I was exhausted. I just didn't have the strength. Justin has so much stamina."

Meanwhile, the brunette minx is adamant she didn't post the now infamous clip of herself and Justin online, saying she filmed the video to prove to a friend she was indeed with the pop star.

She told The Sun newspaper: "I was still in bed with Justin when my friend texted me to say, 'Oi amiga, where are you?' I texted back, 'I'm here in bed cuddling up to Justin Bieber.'

"The video was just for her eyes only. I am really angry with her."

17 reasons why Justin Bieber should not be famous anymore

Ever since he became famous, Justin Bieber has made his fair share of headlines just by living his pop-star lifestyle.

However, he amassed a number of offensive and inappropriate acts that angered many fans and non-fans alike in 2013.

From groping a fan's breast during a meet-and-greet to spitting on his neighbour and threatening to kill him, it's crazy what fame can make a teenager do.

The fact that he has largely escaped prosecution by authorities desipite his bad behaviour is something else we mere mortals can puzzle over.
