The Weeknd and 18-year-old model Bella Hadid have gone public with their relationship.

According to Us Weekly, the couple has been dating since May but was first spotted together holding hands in public on Tuesday night as they partied with Rihanna, Hailey Baldwin and Justin Bieber.

Not only were they spotted together, they also packed on a lot of PDA for the paparazzi to see. Hadid and The Weeknd, whose real name is Abel Tesfaye, hit New York City clubs 1OAK and Up&Down with their pals.

"They were all having a good time," an eyewitness from the club noted. "Bella was all over The Weeknd -- so much PDA," the eye witness added, saying that the couple looked like they were having a really great time.

Justin Beiber seemed to be having a good time with The Weeknd too, as they laughed and talked together at the club, according to the eye witness.

Bella wore a navy blue Sahara Ray Swim Mimi One piece showing off a bit of her nude chest as she walked out of the club holding the 25-year-old singer's hand, HollywoodLife reports.

The Victoria's Secret Model and The Weeknd have been tight-lipped about their rumored relationship for nearly four months.

"Bella is head over heels for Abel, she's so proud to be with him," an insider tells HollywoodLife. "She thinks he's the most talented guy on the planet and the sexiest. They have a pretty wild time together, it's everything you'd expect from listening to his songs."

The couple first started hanging out with Bella's sister, 20-year-old model Gigi Hadid, and Gigi's now ex-boyfriend Cody Simpson.

Bella's older sister Gigi is currently dating Joe Jonas. The couple, dubbed G.I. Joe, might also be getting engaged soon.
