Two sightings in one week! After months of staying under the radar, Bella Hadid and The Weeknd are out of hiding and hitting up parties together all over New York Fashion Week.

The couple — who took their romance public on Tuesday, Sept. 8, at NYC hot spots 1Oak and Up&Down — stepped out again on Thursday, Sept. 10, to attend the Second Annual NYLON Rebel Fashion Party. This time, they were joined by Bella's older sister, Gigi Hadid, and Joe Jonas.

An onlooker tells Us Weekly that the supermodel, 18, and the "Can't Feel My Face" singer, 25, were among the first to arrive at Up&Down after Nylon's NYFW bash ended. At one point in the night, the DJ played The Weeknd's hit single, and Bella stood up and sang along with her boyfriend. They were later spotted holding hands as they exited the club. 

Bella — whose mom is Real Housewives of Beverly Hills star Yolanda Foster — showed off her runway-worthy bod in a long-sleeved, black mock neck crop top, teamed with black pants that had sheer lace paneling along the inseam. The Weeknd (real name Abel Tesfaye) rocked black pants and a printed jacket.

Us exclusively revealed the couple's romance back in May. A source told Us at the time that the model and her musician beau had been spending time with Gigi and Gigi's then-boyfriend Cody Simpson, as well as a pre-split Miley Cyrus and Patrick Schwarzenegger.

On Tuesday, they joined pals Justin Bieber, Rihanna, and Hailey Baldwin at 1Oak, where they weren't shy about showing their affection. "They were all having a good time," an eyewitness told Us of the group. "Bella was all over The Weeknd — so much PDA."
