As if you needed another reason to covet every single item from Rihanna's Fenty x Puma collaboration, how about having RiRi herself ring you up?!

As a special treat for her fans, the singer decided to stop by the Fenty x Puma pop-up in Los Angeles on Tuesday, and went above and beyond in her duties as the collection's designer. Not only did she pose for plenty of photos, but at one point, she also decided to play cashier—and literally started ringing people up at the register.

Could she be any cuter?! If you, too, want a chance at having Rihanna as your cashier, the pop-up will also be open on Wednesday, April 19, at Milk Studios in Los Angeles.
