We spotted Ri-Ri wearing Minx nails in 100 dollar bill and £50 note designs as she accepted the MTV Video of the Year award for We Found Love last week.
Minx nails are a solid nail coating, available in all manner of fabulous designs and colours and loved by all the A-listers.
RIhanna's were applied by Los Angeles based celebrity nail artist, Kimmie Kyees, whose clients also include the likes of Katy Perry, Lady GaGa and Fergie.
