Didn't anyone ever tell these stars to never outshine the birthday girl??
While Gigi Hadid was vixen-like celebrating her 21st year at The Nice Guy in WeHo on Thursday night, her BFFs really took it to the next level!
Taylor Swift, Kendall Jenner, and Kylie Jenner were sizzling!
The pop songstress made her arrival in a sequined black Haney dress and Vetements leather boots to really accentuate her long legs… and fresh new tan! Damn, girl.

Kenny and Ky on the other hand, went the pantsuit route. The supermodel sis showed up in a black and gold embellished two-piece with just a nipply bra for a shirt (again!), while her little sis was showing off her toned tummy in a white cropped blazer, cropped top, and flared silky trousers.
But the newly-turned 21-year-old opted for such a effortless look with her black tank, white hot pants, and wild lace thigh-high boots.
Also in attendance were Khloé and Kourtney Kardashian, Hailey Baldwin, Lily Aldridge, Jaden Smith, Hailee Steinfeld, Naomi Campbell, and the girls of Haim.
Gigi must feel so blessed to have so many friends — though we're sure she missed her beau Zayn Malik, as he was noticeably absent. Whomp!!
Anyway, ch-ch-check out their photo booth pics (below) and their outfits in the gallery (above)!
