Rob Kardashian Brushes Off Rihanna Dating Rumors

By Jocelyn Vena

Rihanna and Rob Kardashian got tongues wagging about them being a potential couple after they were spotted hanging out with a group of friends in Los Angeles this weekend, but Kardashian says there's nothing between them.

Since he had already been linked to Roc Nation's Rita Ora, Rob had many fans wondering if he was double dipping in the record label's roster of hot singers.

But, Kardashian is clearing the air about all those Ri romance rumors, telling Ryan Seacrest, "It was just me and a bunch of girls [at the go-kart place]. 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 pretty insistent that there was no romance brewing with theTalk That Talk singer, he was a bit coyer about his feelings for Ora.

They made headlines earlier this month when they got presumablytemporary tattoos of each other's names on their knuckles. Talking to Seacrest, Rob didn't actually deny their relationship, only sharing, "Rita is in the U.K. I'm just a fan. That's all. I'm a big fan. She does have tattoos."

When asked how he knows about her tats, he teased, "I'm a fan."

In July, after she had been seen out with Rob, Rita told Complexmagazine, "It's not really a relationship. 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."
