Angelina Jolie couldn't be prouder of how her oldest son, Maddox Jolie-Pitt, has turned out.
ET spoke with the 44-year-old actress at Wednesday's premiere of Maleficent: Mistress of Evil in London, where she stunned in a custom Ralph & Russo gown andwas joined by four of her children, 14-year-old Zahara, 13-year-old Shiloh and 11-year-old twins Vivienne and Knox.
Though Maddox was not able to attend the event -- he's at college in South Korea -- Jolie still made sure to praise her 18-year-old son. "I'm so happy for him that [Maddox has] grown up into such a good man," she gushed. "I say that 'cause he's smart and he's doing his work but he's also wild. He's balanced in his teenage years."
"It would be quite lonely if I was doing it all by myself," she confessed. "It's never fun to focus on yourself anyway. When you're all taking care of each other and you're making a game out of it and being silly, it's nice for me as a mom. It's moments."
Jolie continued, "I'm also watching my kids grow up and watching my daughter put on a beautiful dress and figure out the right heels and all that mom stuff. It just means a lot."
