Growing up: Billie Eilish is no longer a teenager – the pop music sensation turned 20 on December 19

Billie’s face was absent from the snapshots, and she simply wrote in the caption: ’20.’

The songstress added cake and party popper cone emojis.

The peppermint-themed cake was white with crushed candy on each of the two tiers.

Additionally it had several full canes sticking out of it, as well as tall, multicolor candles.

The hitmaker’s post came after her older brother and music collaborator Finneas posted a birthday tribute to her on Saturday.

The producer shared three throwbacks with his followers and wrote a touching caption that began, ’20!!!!!!!!! Watching you grow and become the thoughtful, incredibly kind, talented, hilarious and hardworking person that you are today has been the joy of my life!’

In two photos Eilish wore a neon green windbreaker, black pants, and a gold chain necklace while sitting on the floor and leaning her back against a white wall.

Finneas also added a video to his post where Billie playfully nibbles on their mom’s hair while they’re inside a bathroom.

‘I’ll be your #1 fan till the day that I die,’ he added.

And he let his little sister know how much he loves being her older sibling: ‘There is truly nothing I love more than being your big brother. Happy birthday!!!’

Earlier this month the family duo won Variety’s Film Song of the Year award for their song No Time to Die, written for the James Bond movie of the same name.
