Happy 29th birthday to the one and only Timothée Chalamet, otherwise known as the heartthrob of every teenage girl and the bane of every older brother's existence. You may have officially entered the last year of your twenties, but let's be real, you'll forever be 21 in our hearts. May your hair always be perfectly tousled and your acting skills continue to leave us breathless. Here's to another year of making us question our own age and existence. Happy birthday, Timmy!
