Nick Jonas dating Miss Universe?

Nick Jonas is reportedly dating Miss Universe Olivia Culpo.

The 20-year-old singer from pop band the Jonas Brothers was spotted dining out with the 21-year-old beauty queen on Thursday.

The pair were seen enjoying a romantic meal at the Ovest Pizzoteca in New York City, leading to speculation a relationship may be blossoming.

"Nick was leaning in towards her across the table like she was saying something really important," the source told E! News.

Following dinner, the duo apparently walked along the city streets hand-in-hand.

They appeared to be gleeful as they spent more time getting to know each other.

"They looked really happy when they walked together," the insider continued. "Me and my friend both agreed they were, like, swinging their arms all happily."

While the restaurant has confirmed Nick indeed ate there that night, neither he nor Olivia's representatives were available for comment.

The rumoured couple was witnessed leaving his apartment prior to the meal.

They allegedly attempted to hide that they were together on a possible date.

"They were holding hands and there were fans standing outside," the source added. "As soon as they saw the fans, they stopped holding hands."

Apparently Nick took time to talk to fans while his lady continued to traipse the streets on her own.

Nick and Olivia met when Nick co-hosted the 2013 Miss USA pageant with Giuliana Rancic.

The beauty queen by then had been crowned Miss Universe 2012.

Nick has been linked to a sting of high-profile women in the past.

His former love interests include Miley Cyrus, Selena Gomez and Delta Goodrem, according to reports.
