Yesterday, Fox aired a very short, very good Rihanna concert, preceded and succeeded by a football game — you can watch it in its entirety on YouTube (possibly US-only). I caught this live and loved every second of it. The set design, choreography, costumes, the baby bump, and, of course, the music & singing: all pitch-perfect.
Update: I took out the embedded video because for some dumb reason the NFL doesn't allow embeds on that video.
