'Umbrella' - 2007
The breakout, and the first time things get a bit weird. Jay-Z moves out of the way quickly with an inconsequential opening verse, and then it's time for Rihanna to mug, aggressively. She juts her butt out towards the camera in a leather outfit, she co-opts (and improves) Britney's flesh-suit-look from the 'Toxic' video, she dances with a literal umbrella. The effects are wack, but that's one more reason to focus on our girl.
