Bella Hadid, 18, flashes a hint of sideboob in skimpy top as she holds hands with her rumoured boyfriend The Weeknd, 25, during date night in NYC

Bella Hadid and The Weeknd were seen putting on a serious public display of affection on Tuesday night in New York.

Their appearance together seems to confirm the rumours that the model, 18, and the Canadian singer and record producer are romantically involved.

While they've been seen arriving separately at the same venues in the past, they have not previously been photographed together in public.

The duo made little effort to hide their affection for each other, with Bella leading the musician beau by the hand as she strutted out of the Up and Down Nightclub, where they headed after their meal to celebrate rapper Travis Scott's sold-out show at the Gramercy Theatre in New York City.

The model - younger sister of Gigi Hadid - certainly turned heads in her date-night ensemble, flashing a hint of sideboob in a skimpy leotard which she matched with figure-hugging jeans.

Last Month, the pair were seen arriving at different times at Hollywood hotspot The Nice Guy where they joined Bella's sister Gigi, 20, and her beau Joe Jonas, 26.

It's believed that the teen and the producer, whose real name is Abel Tesfaye, have been dating for about four months and they attended the Coachella music festival together in April. 

Confirmation? Their appearance together seems to confirm the rumours that the model, 18, and the 25-year-old Canadian singer and record producer are romantically involved

Get cool city style with a one-piece like Bella

Thought swimsuits were just for the pool? Wrong! Here Bella Hadid is showing us how a one-piece is the perfect piece for city cool too as she hits up New York in this sleek ensemble.

Bella has nailed grunge-glam in her simple bodysuit paired with skinny black moto jeans. To accent her waistline, she wore a belt clincher with the silver buckle and tip. A pair of red color block heels add a sassy finish.

Now there must have been a bit of closet rummaging in the Hadid household last night because we first saw this Sahara Ray swimsuit on Bella's sister Gigi last month. Gigi wore hers with a Stylestalker skirt, Adidas Originals Yeezy sneakers and a VFiles bomber jacket proving that there are a multitude of styling options available with a one-piece.

'They have many things in common and really enjoyed each other's company,' a source told E! News at the time.  

Bella, whose mom is Real Housewives Of Beverly Hills star and former model Yolanda Foster, spent part of the Labor Day holiday weekend in The Hamptons with some friends.

The model shared a photo on her Instagram on Saturday showing herself sunbathing in a tiny black bikini with two galpals, Victoria's Secret model Devon Windsor and Lauren Perez.

She captioned the snap: 'Smileeeeeyyyys.'

She's likely in town for Fashion Week that kicked off Tuesday.

On August 31, Bella dropped big hints that she's set to feature in Victoria's Secret PINK Christmas campaign alongside her friend Devon and model Rachel Hilbert.

Rachel, 20, became VS PINK's official spokesmodel back in June, while Devon, 21, made her VS Fashion Show debut in 2013.
