Selena Gomez and Nick Jonas were "very flirty" at the MTV VMAs

A source told the New York Post's Page Six: "They were very flirty. He kept whispering in her ear."

Nick and Selena, 23, had an on-again, off-again relationship for two years until 2010 and recently had dinner together with a group of friends.

The 22-year-old heartthrob said: "We kind of ran into each other a couple of weeks ago, like walking in Venice [California]. We were both with separate groups of friends and we ran into each other.

"I put a dinner together with a bunch of really great people, like the Haim girls, who I love. They're awesome. They're the best. It was a big group of people and we all had a great time. We connect in that sense. It was nice to connect and just catch up. I'll leave it there!"

The 'Jealous' hitmaker recently split from longterm girlfriend Olivia Culpo, while Selena had a brief fling with DJ Zedd after splitting from Justin Bieber.
