Rihanna was shining bright like a diamond at the Zac Posen Fashion Show during the Mercedes-Benz Fashion Week on Monday evening in New York City.

The ‘FourFiveSeconds’ songstress kept it low profile in a beautiful maroon, baring some cleavage.

The Zac Posen fashion show was a star-studded event, with big stars like Mary J. Blige, Christina Hendricks, Katie Holmes and Orange is the New Black’s Uzo Aduba, all gracing it.
