One Direction's Niall Horan dating Joe Jonas' ex Jessica Serfaty?

One Direction singer Niall Horan has been romantically linked to Joe Jonas' ex-girlfriend Jessica Serfaty.

The 22-year-old singer spent the weekend in Los Angeles and Las Vegas with former America's Next Top Model contestant Jessica Serfaty, who split from Joe last month after a brief fling, reported Female First.

"Niall and Jessica have loads in common and enjoy spending time together. He met up with her at the UFC fight in Las Vegas on Saturday before inviting her to the football in LA the following night," a source said.

They chose seats next to each other and were flirting in the box. Niall even pretended to pull a wrestling move on her for a laugh. They seemed to be getting on really well."
