She might be a full-blown supermodel who’s worked for a ton of distinguished brands, but Gigi Hadid has only just turned 21-years-old.

That’s right, the model finally celebrated her huge milestone birthday over the weekend – and naturally, it was a pretty star-studded squad affair.

Gigi started things off with her family, including siblings Bella and Anwar, but was soon joined by her (kind of)in-laws as Zayn Malik’s sisters and mum joined them for a gorgeous trip to the Californian coast.

Zayn not only shared an adorable picture of him and the Malik ladies, but he also posted a sweet action shot of him, Gigi and Bella exploring the pretty landscape.

Well, the fun didn’t even stop there for the birthday girl, as she even spent the end of her weekend jetting off to Coachella with Taylor Swift and Calvin Harris to watch his closing set at the festival.

Calvin was quick to Snapchat the two girls having a gossip on the plane, while Gigi just had to show some love for Taylor and her INTENSE cake making skills.

So all in all, not the worst weekend, we guess.
