Naturally, Rihanna [1] is staying ahead of the trends with her latest red nail polish colour [2]. The singer, designer, and beauty entrepreneur wore the vibrant hue to the Diamond Ball, an event that supports the Clara Lionel Foundation [3], which is the star's non-profit to benefit impoverished communities worldwide.

Earlier this year, manicurist and brand founder Jin Soon Choi told POPSUGAR that this colour would become one of Fall's biggest nail polish [4] trends. "Red, burgundy, berry — these deep shades are emblematic of Fall and represent a sophisticated twist on quintessential bright red nail polish while still being feminine and classic," she said. "They are timeless colours that cross from classic to modern and feminine to bold — making them perfect for all Autumn occasions."

In addition to being on top of her nail game, Rihanna [5] also aced her makeup. The singer's makeup artist Priscilla Ono [6] revealed that her glowing skin, monochromatic red lips, and cat-eye were exclusively created with Fenty Beauty [7] products.
