Rob Kardashian Girlfriend: Insistently Denies Ties to Rihanna and Rita Ora [POLL]

MTV reports that Rob Kardashian insists he is not involved in a three-way romance with pop stars Rihanna and Rita Ora. In fact, the brother of the infamous Kardashian sisters claims that he is merely "just a fan" of the two hit singers.

Rumors of a potential Kardashian-Rihanna hook-up began to spread when the duo was spotted partying and go-karting together earlier this week in L.A. But to clear up the air, Kardashian recently told television host 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."

Recent controversy surrounding Rihanna's love life has involved more than just the Kardashian rumors - the "Where Have you Been" songstress has reportedly been "text flirting" with Hollywood's newest hot bachelor Robert Pattinson (following his highly-publicized breakup with "Twilight" co-star Kristen Stewart).

As for the dating rumors surrounding 25-year-old Kardashian and 21-year-old Ora, Rob claims, "Rita is in the U.K. I'm just a fan. That's all. I'm a big fan. She does have tattoos" (he then goes on to explain that he's "a fan" of tattoos...).

The British singer/songwriter also spoke of the matter with Radio 1 on Wednesday, stating, "I've never been in love. Is that a good thing or a bad thing? I think it's sad... I'm single at the moment. I'm a girl and I would love to meet a boy, but I have no time and it would be unfair. I'd be like a ghost, an invisible girlfriend in a relationship."

So there you have it, Rob Kardashian is supposedly "just friends" with two of R&B's hottest stars. What do you think of the matter?
