Kylie Jenner And Other Celebs Attend Gigi Hadid's Epic Birthday Party

Gigi Hadid's week-long birthday celebrations continued last night in the most typical 21-year-old fashion.

After turning the big 2-1 on April 23, Gigi celebrated with a sweet birthday lunch with the fam, hopped a private jet with Taylor Swift and Calvin Harris and took a low-key beach trip surrounded by her family and boyfriend, Zayn.

Of course, like anyone who just became the legal drinking age, the birthday was not complete without a true late-night celebration in LA.

Last night, everyone who's anyone even kind of claiming to be part of a Hollywood #girlsquad got together at The Nice Guy in LA to party with the supermodel and, you know, enjoy her first few tastes of alcohol by her side.

Taylor Swift already baked her a birthday cake, but she certainly wasn't going to miss out on the club celebration with her bestie.

Posing beside her model pals Gigi and Lily Aldridge, Taylor also threw a not-so-subtle shoutout to boyfriend Calvin Harris, captioning the photo with the title of his new single, "This Is What You Came For."

Kylie proved once again she is just like us by rolling up to the celebration jamming out to Beyoncé's Lemonade...with Hailey Baldwin.

Kendall, Khloé and Kourtney were also in attendance to make it a true family affair (minus Kim).

Kendall was feeling really festive in a sheer bra, and on Kylie's Snapchat, she gave us all a good look at...everything.

And just like all of us at our own birthday parties, Gigi was just happy old and new friends were getting along.

She captioned the post,

When high school and post-high-school BFF's are united.

It's unclear whether this marked the end of birthday celebrations, but naturally, we all just want to know: Where was Zayn?!
