One Direction singer Niall Horan has sparked rumours he is dating model and actress Jessica Serfaty after the pair were reportedly spent the weekend together in Las Vegas.

Irish singer Niall, 22, is reported to be getting close to the 24-year-old Blood Brothers actress, after they were photographed together at the Ultimate Fighting Championship between Nate Diaz and Conor McGregor last Saturday (05Mar16) at the MGM Grand Garden Arena in Vegas.

The next day they were spotted sitting next to each at another event, this time a football match between LA Galaxy and DC United at the StubHub Centre where Niall had hired a private box for the pair.

A source told British newspaper The Sun: "Niall and Jessica have loads in common and enjoy spending time together.

"He met up with her at the UFC fight on Saturday before inviting her to the football the following night. 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."

Earlier this year the former America's Next Top Model contestant was linked to singer Joe Jonas after the pair enjoyed a romantic skiing trip in California.

The young model gave birth to a son, Roman, when she was 16. She married husband Ididia Serfaty aged 17, but the pair divorced in 2013.

The Best Song Ever hit maker Niall, was previously romantically linked to Australian model Melissa Whitelaw who he split up with last summer. And last December (15) the singer was photographed kissing pop star Selena Gomez, at the X Factor final.

Niall's representative declined to comment on his personal life.
