Meanwhile, Hailey also brightened up the winter evening, sporting an oversized scarlet Formula 1 jacket and pleather pants for the friends' low-key dinner.

It was a well-earned evening off for the supermodel, who returned straight to work after jetting back from the UK.

The supermodel looked lovely in a men's striped shirt as she modeled a long necklace while inside a building in Brooklyn, New York.

Earlier the 21-year-old sister of Gigi Hadid had on leather slacks, a shiny bomber jacket and heavy boots as she arrived at the location.

Hadid was styled like an 80's punk rocker pre-photo shoot on Monday. She wore slick leather pants, durable Louis Vuitton boots, and a black peaked cap.

The IMG model battled the New York chill with a black hoodie and a black bomber jacket.

A leopard print fanny pack was thrown over her shoulder as she carried an extra-large water bottle, sunglasses, and her cell phone.

The brunette bombshell was spotted shooting in a rustic diner in NYC. 

Hadid bared a good amount of cleavage in an off-the-shoulder striped blouse that was barely buttoned. 

A necklace that was shaped like an arrow dangled down her chest and she wore a pair of blue trousers that were tied in a bow at the waist.

Her hair was curled pin-up style and her eyes popped thanks to a heavy cat-eye.

The daughter of Real Housewife Of Beverly Hill star Yolanda Hadid left her shoot mid-day in a pair of ripped denim and the same black bomber jacket she'd been wearing earlier in the day—sans a bra. 

Love! Bella shared a few snaps on Instagram with glowing pink hearts floating around the top of her perfectly coiffed hair

She hid behind orange tinted sunglasses and walked in blue and red suede stilettos.

The looker was with an entourage for what we can only assume was a lunch break, considering she was still wearing the set jewelry.

Bella shared a few snaps on Instagram with glowing pink hearts floating around the top of her perfectly coiffed hair.

Later in the afternoon, the supermodel seemed to be famished as she inhaled a sandwich behind the guise of a bear filter and glasses.

The daughter of Mohamed Hadid—a Jordanian-American—continues to support the Middle East as turmoil escalates amidst Trump drama.

Just days ago, Bella took to the streets with anti-Trump Palestinian protesters in London.

The brunette beauty stuck out like a sore thumb as she marched in her red gown and large white fur coat that she'd worn to the TAG Heuer’s flagship store launch.

We're still waiting for love rumors to be confirmed by The Weeknd—also known as Abel— and the runway model.

The couple began exclusively dating back in July 2015 before going their separate ways in November 2016. 

In January 2017, the Starboy singer began dating the infamous Selena Gomez, but that quickly ended in October. 

Sources recently told E! that Abel and the leggy model have been spending time together. 

'Abel reached out to Bella asking to hang out and catch up, and she decided to see him and see where things go. She knows that if they don't date again, they can at least be good friends,' the source said.
