Wochit News - Rihanna Turned Down Super Bowl Halftime To Support Colin Kaepernick - Rihanna is said to have turned down an offer to headline the Super Bowl halftime show in 2019, out of support for Colin Kaepernick, the former San Francisco 49ers quarterback who took a knee during the national anthem to call attention to police violence against people of color and racial injustice. The pop-R&B singer was among several artists in the running for the headline slot at the 2019 Super Bowl.
