Saturday afternoon, racing around the track with colorful helmets in tow. Rob was still dressed casually in a vest and brown trousers with Nike trainers and a New York Yankees baseball cap. The Bajan-born beauty was seen enjoying a go-karting date with none other than Rob Kardashian, on Saturday night. Advertisement Kardashian, 25, and Rihanna, 24, kept it casual when they squeezed into a pair of go-karts at Racer's Edge Indoor Karting in Burbank, Calif.

He kept his head down and attempted to maintain a low profile upon entering the hotspot, but his trademark tattooed arm identified him. The British singer has been compared many times to Rihanna for both her styling and sound of music.
