Gigi Hadid had the best bday ever.

What are friends for?

Gigi Hadid turned 21 years old on Saturday, and continued the celebrations on Sunday with her close pal, Taylor Swift, and the singer's boyfriend, Calvin Harris. Calvin and Gigi both posted Snapchats of the three of them on a private jet en route to Coachella -- which Calvin headlined for the second weekend in a row -- with Taylor sweetly presenting Gigi with a cake.

"I love you," Gigi captioned a Snapchat pic of the "Blank Space" singer holding the delicious Sweet Lady Jane Triple Berry cake.

"Cake(s) on a plane," Calvin also Snapchatted, poking fun at Samuel L. Jackson's 2006 film, Snakes on a Plane.


Gigi later joked about being the third wheel to the A-list couple.

"Thank you guys so much for having me on your romantic date," Gigi cracked on Snapchat.

"Thanks for coming on your birthday weekend, that's great. Wow," Taylor deadpanned back.

"F*cking pleasure," Calvin simply replied.

Prior to Sunday night's festivities, Gigi spent her big day with her boyfriend, Zayn Malik, taking a family trip to the beach. Zayn Instagrammed a picture of himself with both Gigi and the model's younger sister, Bella, with the birthday girl sporting a cute gingham one-piece.

And it looks like Zayn invited his own family to the celebrations too. "Chillin with the fam," he captioned another black-and-white beach pic, this time featuring his mother, Tricia, and his three sisters.

"Best birthday," Gigi wrote about the relaxing day.

Interestingly enough, Zayn and Calvin got into a Twitter spat over Taylor last August, when Calvin called out Zayn over what he saw as the former One Direction member throwing shade at his girlfriend over her thoughts on making money in the music industry.

"I suggest you calm your knickers before them dentures fall out," Zayn tweeted at Calvin at the time, also calling the 32-year-old producer a "d*ckhead."
