One Direction's Niall Horan Dating Rumors 2013: Rumored girlfriend Tamera Foster spotted getting cozy w/ 'X-Factor' co-star Sam Callahan

Earlier this week, reports were flying in claiming that One Direction's Niall Horan had fallen for X-Factor singer Tamera Foster during a recent episode taping. Foster furthered these claims by talking at length about how she and Niall had been talking in private through flirty texts and phone calls. But now Tamera was spotted cozying up to her co-star Sam Callahan! What about Niall?

"Niall and I have been talking in private," Tamera exclaimed. "He's the most famous person in my phone after Nicole Scherzinger. I hope he fancies me - he's cool."

"I spent most of my time with Niall. He's really fun and very immature," she said. "I get really hyper before I sing, so I was ­ practically bouncing off the walls. I was singing, 'yeah, I'm ready, I'm ready,' and Niall started singing, 'I'm ready, I'm ready' along with me. He asked for my number and we've been talking."

But if she's so into Niall, why are we now seeing her in matching outfits with Callahan?

Either way, it doesn't look like Sam is interested in a romance with Tamera.

"I'm not really looking for a girlfriend," the X-Factor singer revealed. "I've got a lot to focus on at the minute and me and Tamera are just really close. We talk a lot and spend a lot of time together but we're just mates."

So do you think Tamera is going for Niall or Sam? Or maybe she's going for both? Either way, she's definitely getting our attention!
