The Come and Get It singer openly held hands with sales executive and New York University graduate Samuel Krost as they left popular hotspot Cipriani, where they had reportedly been spotted talking and laughing at a table with model Cully Smoller.

Eyewitnesses tell U.S. news show Entertainment Tonight that at one point in the evening, Selena even appeared to sit on Samuel's lap and wrap her arm around him, sparking rumours of a new romance.

Selena is believed to have met Samuel through mutual friend, model Gigi Hadid, whom he and Cully recently accompanied to Heidi Klum's extravagant Halloween (31Oct15) bash in the Big Apple.

Selena's outing with Samuel came after she attended the Glamour Women of the Year Awards, where honourees included Reese Witherspoon and Kim Kardashian's stepfather, Caitlyn Jenner.

Selena, 23, has yet to comment on whether she is more than just friends with Samuel, but if that rumoured relationship doesn't work out, there's still one man who is interested - her ex, Justin Bieber.

The former couple dated on and off from 2011 to 2014, and on Monday (09Nov15), Justin admitted he would never rule out another reunion with Selena, his first love.

"We have a lot of history together and I am sure it could possibly happen," the 21 year old told U.S. talk show host Ellen DeGeneres. "I think we are both just on our own journeys and figuring ourselves out and I think maybe once we figure ourselves out, we can come back and make an awesome duo or she finds someone awesome and I'll find someone awesome. I just want her to be happy."
