The 'Diamonds' singer often sets tongues wagging with her raunchy ensembles (who remembers the see-through dress RiRi wore to the CFDA Awards?) but she opted for a much more demure look while performing in Washington.
Taking to the stage at The Concert for Valor: Saluting America's Veterans, RiRi glimmered in a dazzling sequin ensemble while belting out her famous tunes.
The Bajan beauty wore a black sequin top teamed with matching skin-tight trousers, all topped off with a coordinating shimmering cape. Amazing, right?!
She added even more glitz and glamour by sporting a huge diamond-encrusted statement necklace and heaps of silver rings, while lengthening her pins with barely-there black sandals.
In true RiRi style her stiletto nails were lacquered a striking red hue and she went for bold rouge on her pout too, finishing with a flick of liquid liner, perfectly-defined brows and flawless, glowing skin.
And check out that super-impressive barnet! The songstress showcased sleek, smooth and poker straight locks which fell way below her waistline. Her bonce does look fab, although we hate to think how long it takes to wash and dry...
