They'll finally be legal adults, which comes with all sorts of perks. All of these celebrities have built extremely successful careers at such a young age.

The list of celebrities that are 18 next year includes JoJo Siwa, a dancer-singer-actress who got her start at a young age on the reality show Dance Moms. Since then, Siwa has become a star in her own right, launching her insanely popular YouTube channel and releasing poppy hits like "Boomerang" and "Kid in a Candy Store." 

Actors Jack Dylan Grazer, Jaeden Martell, and Wyatt Oleff will be turning 18 years old. All three appeared as members of the Losers' Club in the 2017 adaptation of Stephen King's It. Since then, Oleff has also starred in the Netflix series I Am Not Okay With This.

Another celebrity born in 2003 is Johnny Orlando, a YouTuber who gained notoriety for his covers of songs by artists including Justin Bieber and Austin Mahone. As of December 2020, his channel has 4.5 million subscribers. Not bad for someone who hasn't even reached official adulthood yet!
