The big day may have been last week, but the supermodel rang in her 21st birthday on Thursday with a star-studded bash at Hollywood hotspot The Nice Guy with her closest friends and family.
Hadid strode into the bash hand-in-hand with BFF and fellow model Kendall Jenner. She sported a black, top with white short-shorts and thigh-high, lace boots.
Jenner wore a pair of detailed, high-wasted pants with a matching jacket over a sheer black bra. Hadid's mother, Yolanda Hadid, accompanied her into the club as well.

There was a photobooth set up in the club, where party-goers cuddled up to pose for pictures. And Swift made sure the #squad was in full effect.

"This is what you came for. @gigihadid @lilyaldridge," Swift captioned a photobooth snap of herself, Hadid and Lily Aldridge.
Kourtney stepped into the booth several times for photos with the birthday girl, as well as pics with Khloé and Smith.

Hadid looked to be in high spirits at the event, sporting a big smile the entire night. And with good reason; her mother and stepfather, David Foster, put their differences aside to attend the bash.
The exes did not interact much at the party, though. Foster mostly stayed close to his friends, sitting and eating.

Hadid's boyfriend, Zayn Malik, got to the party at around 1:30 a.m. and danced away the night with Hadid and Swift. He and his leading lady couldn't keep their hands off of each other at the birthday bash.
All of the guests appeared to enjoy the bash, and for the Jenner sisters, the party started a bit earlier.
Kylie posted a series of Snapchats of her, Kendall and model pal Hailey Baldwin jamming to Beyoncé's Lemonade on their way to the event.
