The Keeping Up With The Kardashians star partied in West Hollywood with her sisters and celeb crew, and her boyfriend Tyga bought her a Ferrari (casual) and Zayn Malik made a sneaky appearance.

And the icing on the cake was well, the cake.

The pout-princess received a cake in the shape of giant lips, as it’s the feature she’s best know for. In fact, they’re now known as the most famous lips on Instagram. We’re sure her mum’s very proud.

Not just a fun birthday cake theme, Kylie’s lips have also been at the centre of controversy, too.

Remember the#KylieJennerChallenge, when teens sucked in their lips with a shot glass to mimic the star? It wasn’t a pretty sight. Also earlier this year, she admitted to having had lip fillersto literally nobody’s surprise.

You just have to take a glance at her changing face timeline here to see that.
