Rihanna: 'Cheers (Drink To That)' Music Video (VIDEO)

Perhaps it's appropriate that, as the East Coast braces for Hurricane Irene this weekend, Rihanna releases her new music video for "Cheers (Drink To That)," a breezy, tribal party-rock song that samples Avril Lavigne's "I'm With You" and serves up a nostalgic toast to summer. We see behind-the-scenes shots of sailing, drinking coconuts and clinking cups of what looks suspiciously like Kool Aid. Not that it's keeping us from Cheering, and Drinking To That, though -- especially not on this weekend.
