The Barbadian beauty, who has shocked fans in the past with her seriously sexy and revealing outfits, opted for something a little more elegant at London's O2 Arena.
Rihanna, who recently turned 28, posed for pictures in a long and floaty lilac dress, which had been adored with dozens of sparkling beads. Beautiful!
She wore her hair in a straight bob, kept her make-up simple and accessorised with strappy silver sandals and a couple of silver rings.
Fans cannot wait for her performance tonight, as it is the first time Rihanna has taken to the stage for such a big event in a long time.
Earlier this week, it was revealed Rihanna will be headlining at this year's V Festival, however she was forced to cancel an appearance at the Grammys earlier this month due to illness.
Bring on tonight!
