Rihanna looked smokin' hot at the 2011 Billboard Music Awards.

While the 23-year-old singer turned up the heat with her sexy "S&M" performance alongside Britney Spears, she also got our pulses racing with her fiery red bob. The voluminous and chin-length hairdo paired well with her white Max Azria suit, and we loved how the coral blush and lip gloss warmed up her caramel complexion.

But what about Rihanna's stunning eye makeup?

The Bajan beauty accentuated her perfectly, arched brows with lavender eye shadow and mascara to instantly brighten her hazel eyes.
