Kelly Clarkson brings the house down as she performs the National Anthem on Sunday (May 29) at the Indy 500, held at the Indianapolis Motor Speedway in Indianapolis, Indiana.

The 29-year-old singer performed with Seal – David Foster accompanied the duo!

“Um these cars are averaging around 220 mph?! Hanging at the Indy 500 having fun with my brothers and friends!” Kelly tweeted, adding that she thought Danica Patrick had the coolest car on the track.

FYI: Kelly is wearing Swarovski‘s silver shade “Fit” pierced earrings and a pewter two-toned “Appolon” statement ring.
