So Nasty, So Rude: Rihanna Tickled As Ariana Grande Sexes It Up For 'Problem' Performance

After breaking the iTunes chart records this week and having her new single ‘Problem’ top the platform in less than a few hours after release now on course to sell over 300,000 copies, Ariana Grande made her way to the iHeart Radio Music Awards on Thursday evening to perform the new track.

The pint size singer performed to a room complete with Pharrell, Usher, Diddy, Drake and more, but leave it to Rihanna (who moments before, won an award for best fan base, against Ariana) to take a sip of her cocktail, and have a shady laugh at the young pop star for her attempt to get sexy (3:08 mark). Shade or nah??
