Angelina Jolie’s son Maddox is 18 years old — can you believe it?

Along with his mom, Maddox celebrated the occasion in Cleveland. Loung Ung, author of the book First They Killed My Father, which Angelina turned into a film in 2017, posted photos to her Facebook page.

“Angelina and Maddox visited me in Cleveland this past week to toast Maddox’s upcoming 18th birthday!” she wrote. “We started with lunch at Market Garden Brewpub and a visit to Ohio City Farm/The Refugee Response Program and Cleveland Museum of Art! I met Maddox when he was just a year old and today he turns eighteen and going off to college! So proud! Happy Birthday, Maddox!”

As previously reported, Maddox will be moving to South Korea in the fall for school where he will study biochemistry.
