Rihanna kicked off her long-awaited ‘LOUD’ tour last night (June 4) at Baltimore’s 1st Mariner Arena, topping off the raunchy show by treating one lucky female fan to a lapdance.

Following after Nicki Minaj’s famous dances and even after Rihanna’s ex-boyfriend Chris Brown had a go, the ‘S&M’ singer topped all as she laid the fan down on a revolving platform and straddled her as the band played ‘Loud’ track ‘Skin’.

The crowd roared as Rihanna grinded in a skimpy white bondage outfit – the same one from her Billboard Music Awards performance with Britney Spears – after which the platform sunk into the floor.
