Move over Kim Kardashian. The celebutante is usually at the forefront of family dating rumors, as her relationship with Kanye West deepens. Her little brother Rob found himself in the dating hot seat this past weekend, as rumors abounded that he was stepping out on “casual” lady love Rita Ora with Rihanna.

Rob called into Ryan Seacrest’s morning radio show to clear up the rumors and to clarify what’s going on with Ora, who herself went on record to say that their relationship is not that serious.

While many dudes might pat Rob on the back for enjoying the company of two beautiful, famous and talented women, it also made him look like a two-timer. He was spotted at a racetrack with RiRi only due to the fact that they were celebrating a mutual friend’s birthday. “It’s because Rihanna’s a friend, and she is friends with my friend Capricorn, and it was her birthday. Then we all went out to celebrate our friend’s birthday. It was fun! It was a good night,” he said.

Personally, we didn’t think that RiRi was all ’bout Rob. She’s still pining for Chris Brown, which you’d know if you saw her Oprah interview!

He also downgraded his relationship with Ora, with whom he got fake name tattoos a few weeks back.

He says he is “just a fan. That’s all. I’m a big fan.” A big fan huh? That sounds dismissive or like he was trying to throw Seacrest off the scent.

Whatever the case, both Kardashian and Ora have been vocal about the fact that they are not in a heavy, committed relationship, which could be either the truth or just how they spin it in the media. With Ora hotter than lava as she readies the release of her debut ‘Ora,’ she may want to play up the fact that’s she’s single to a male audience. Or not.
