Bella Hadid was spotted cosying up to a mystery man

An insider told the New York Post newspaper's Page Six column that the two appeared "very flirty" at the party and were "whispering to each other at various points throughout the evening."

It's understood that the mystery man was a fellow guest at the bash, along with the likes of Kendall Jenner, Bella's sister Gigi, Ellie Goulding, Gwendoline Christie, Derek Blasberg and Winnie Harlow.

Earlier this month, Bella admitted her split from the 'Starboy' singer - whose real name is Abel Tesfaye - was "hard" to deal with.

She said: "It was my first break-up...and so public. As an outsider, you might think I handled it so well, but it's always in your heart, and you always feel it very heavily. It'll be hard for a while. Love hurts, but you have to pull through. But I'll always respect him, and I'll always love him. Sometimes you want to be sad about it or handle it differently, but at the end of the day, you never want to burn a bridge that you've fought so hard to build."

The Weeknd has now moved on with Selena Gomez and is said to be besotted with the former Disney star.

A rep for Bella declined to comment on her reported mystery man.
