Rihanna has been pictured posing in a revealing white suit as she snarled backstage after her show in LA last night (8th April).
The 'You Da One' singer performed in front of a sold-out crowd at the Staples Center in California and donned the suit jacket and a pair of tiny white shorts as she posed for pictures.
The outfit exposed her huge chest design tattoo – which is a tribute to her late grandmother who passed away last year.
The star's show was watched by a host of celebrities including model Rosie Huntington Whitley and rapper Tyga.
Christina Aguilera and Jesse Metcalfe were also in attendance for the gig.
