On another note, Rihanna?s second single, "Unfaithful," continues its Top 10 reign on the pop and digital charts, while her second album, "A Girl Like Me," turns the corner past RIAA platinum for U.S. sales in excess of 1 million units.

It has also been announced that Rihanna has been chosen to represent Clinique's "Happy" fragrance in a new campaign to begin in December. Rihanna's fellow Def Jam artist Ne-Yo (who co-wrote "Unfaithful") has been commissioned to compose an original song, "Just Be Happy," to be recorded by Rihanna says Clinique, "expresses the spirit of happiness in music much the same way Clinique Happy does in fragrance."
