While inside the bash, the Grammy-winning superstar Instagrammed a stunning black-and-white photobooth shot of herself with the birthday girl and their Victoria’s Secret Angel gal pal Lily Aldridge.“This is what you came for,” the “New Romantics” singer, 26, captioned the photo.

In two more follow-up pics, T. Swift posed with Aldridge again, plus the ladies of Haim. “We say nothing more than we need,” she wrote alongside one of the fun snaps.

Aldridge, 30, shared a post of her own, which featured Swift, Hadid and Hadid’s mom, Real Housewives of Beverly Hills star Yolanda Foster. “Happy birthday G,” Aldridge wrote.
And it wouldn’t be a party without an appearance from the Kardashian-Jenner family. Kourtney Kardashian wished the Sports Illustrated Swimsuit stunner a happy birthday by posting a sweet image of herself and younger siblings Khloé Kardashian and Kendall Jenner huddled around Hadid.
The mom of three, 37, also uploaded a captionless ‘gram of herself and Khloé, 31, hanging out with Jaden Smith.
Kourtney and Khloé stunned in similar plunging black jumpsuits. The former Kocktails With Khloé host put her fit frame on display with the help of strategically placed sheer paneling. Jenner, 20, who arrived at the bash with Hadid, flaunted her flat abs in a dotted lace bra by Anine Bing, worn underneath a baroque pantsuit by Naeem Khan.

The youngest member of the Keeping Up With the Kardashians clan, Kylie Jenner, looked white-hot in a crop top teamed with a zip-up packet and wide-legged trousers.

Hadid’s fellow model and BFF Hailey Baldwin was also in attendance. Baldwin shared a cute pic of herself kissing the guest of honor’s cheek, writing, “Happy 21st @gigihadid.”
Baldwin, 19, showed off her toned legs in a Tamara Mellon nude mesh dress. She topped the sexy look off with a sparkling choker and heels by Bionda Castana.
