Rihanna advertises Dior sunglasses line on vacay

After wrapping the North American leg of her 'ANTi' world tour, Rihanna took a vacation to Turks & Caicos. Of course vacationing doesn't always mean shunning work entirely. Rihanna's promotional duties were in full effect when she posed it up in Dior shades from her new line. These new pics are badass, and the colours are mesmerizing.

Rihanna has partnered with Dior for their new sunglasses line, which is simply named 'Rihanna' and hits Dior retailers this month.
