Angelina Jolie says she's already missing son Maddox, who has flown the coop to go to university

It's a bittersweet goodbye when your oldest leaves home.

It seems only yesterday that Angelina Jolie adopted her eldest son Maddox, yet in the blink of an eye he has grown up and the now-18-year-old has flown the coop to start university.
His famous mother dropped him off at Yonsei University in Seoul, South Korea, last week and has revealed that she is "proud" but understandably bereft.
Maddox will be studying biochemistry.
Angelina, who lives with her other five children in California, spent time with Maddox at the university campus helping him settle in before bidding farewell to him at the airport. The Maleficent star shared with media that saying goodbye to him was difficult, admitting she already missed him - and had to let out an 'embarrass-your-children ugly cry', too.
She told Entertainment Tonight: "I had the big glasses, and the amount of times I turned and waved. I do know it was the one moment in my life I think I turned around six times before the airport just… And he sweetly stayed and kept waving, knowing that I was going to keep turning around. You could feel he knew he couldn't leave.
"I am very proud of him. He is ready — he's good. I miss him, I miss him."
She said she's already set with plane tickets to visit him.
Angelina adopted Maddox in 2002.
All five of Angelina and ex-husband Brad Pitt's other children, Pax, 15, Zahara, 14, Shiloh, 13, and twins Knox and Vivienne, aged 11, were also at the airport to wave off their big brother.
Angelina, 44, revealed: 'When you know that your kids love each other and you see the way they all – without any kind of prompting or pushing – give each other notes, hug each other, take each other, support each other, then you feel like they're going to be okay and they're always going to have each other."
Maddox was the first of Angelina's six children to come into her life when she adopted him from his birth country, Cambodia, in 2002. Four years later, her then-partner, Brad Pitt, also adopted Maddox although it's understood Pitt was not at the emotional send-off.
Maddox and Angelina have always shared a special bond, with Maddox even joining his humanitarian mother's side in Cambodia to work with her on the movie, First They Killed My Father.
Of working with his mum he told People, "[She's] fun, funny, and easy to work with. She's a wonder."
Angelina said Maddox had encouraged her to make the film about his home country, revealing he even studied documentaries to help her with the script.
