Rob Kardashian certainly seems to have cheered up from last night’s tear-filled episode of Keeping Up With the Kardashians.

The reality star was spotted over the weekend getting chummy with Rihanna, go-karting with the pop star by day and clubbing by night.

Along with a large group of friends, the pair were first seen palling around at Racer’s Edge Indoor Karting in Burbank, California. After that escapade, the posse reportedly headed to Playhouse nightclub in Hollywood.

So do we have a new couple on our hands? Looks like we’ll just have to wait and see. Rob has been rumored to be dating Rihanna look-alike, Rita Ora for some time now and has even recently tweeted a photo of himself with her name inked (in pen) across his fingers. 

Rita, on the other hand, has stayed mum about whatever relationship she might have with the reality star. 

Rob's family make their lives public. Me? I'm very private,” Rita told Glamour magazine last month. “He's a great friend. But the only relationship I'm having now is with the tour bus.”
