New sexy dance track, "Who's That Chick," from Rihanna featuring DJ/producer extraordinaire David Guetta. Her new album is shaping up to be fit perfectly for the clubs worldwide! And if you don't know who David Guetta is, then you just need some reminders. Kelly Rowland's "When Love Takes Over" and Akon's "Sexy Chick" from last year were both from his platinum-selling/Grammy-nominated One Love album...not to mention his work on the massive Black Eyed Peas' hit single "I Gotta Feeling." Give it a listen... :)
