R-Patz leaves Jay-Z gig with braless Oz singer Sia Furler

Robert Pattinson stepped out with a braless Aussie singer Sia Furler, after attending the Jay-Z and Justin Timberlake concert at the swanky Roosevelt Hotel.

While the 'Twilight' hunk tried to avoid the photogs, his lady friend Furler, 37, got some extra attention from the waiting paparazzi - thanks to her sheer top that left very little to the imagination and flashed her bare breasts, the Sun reported.

The blonde beauty and Kristen Stewart's former beau became close friends after she recorded a song for the soundtrack of the third movie in the 'Twilight' franchise.
