After Rob Kardashian was spotted hanging out with Rihanna on Saturday, the rumor mill went into overdrive speculating that the two were in cahoots. And what happened to Rita Ora, who Kardashian was said to have been dating?

Yesterday, Rob cleared the air on Ryan Seacrest's radio show.

"It was just me and a bunch of girls [at the go-kart place]," he told Seacrest. "It's because Rihanna's a friend, and she is friends with my friend Capricorn, and it was Cap's birthday. We all went out to celebrate our friend's birthday. It was fun. It was a good night."

While he was adamant that there is nothing going on between him and Rihanna, more surprising was his stance on whether or not he's dating Rita Ora. The pair got tattoos of each other's names on their hands earlier this month.

"Rita is in the U.K.," he said. "I'm just a fan. That's all. I'm a big fan. She does have tattoos."

Way to dance around that question, Rob. But he's not the only one doing that shuffle.

"It's not really a relationship," Ora told us in Complex's August/September cover story. "It's not that intense. He's a cool guy. We're close. We're good friends. I got his back and he's got mine."
