Rihanna and Rob Kardashian were spotted spending the day together Saturday, going go-karting at the Racer's Edge Indoor Karting in Burbank, Calif., and then partying later on at Playhouse nightclub in Hollywood.

The "Where Have You Been" singer sported an oversized lacy letterman's jacket for the fun occasion, speeding around the track with Kardashian and a group of friends (and winning the race against the E! reality star).
