Even before Knox Jolie-Pitt arrived, Angelina Jolie and then-husband Brad Pitt already had four kids — Maddox, Pax, Zahara and Shiloh (all but the latter adopted) — but the media went crazy when they learned that the Hollywood power couple, dubbed Brangelina, were having twins.

In May 2008, the Girl, Interrupted actress, 43, and the World War Z star, 55, confirmed to the world that they were expecting twins, only their second and third biological children. The pair headed to a hospital in Nice, France, for some peace and privacy, but that didn’t change the fact that flocks of reporters and photographers camped outside, waiting for the birth. Finally, on July 12, 2008, Knox and Vivienne Marcheline were born.

The twins’ births were heard around the world, with the first pictures of the duo reportedly being sold for $14 million — making it the most expensive celebrity photos ever taken, with all proceeds were given to charity. Quite the way to enter this world, huh? But now it’s time we focus on one-half of those famous twins, Knox, and see just how much he’s changed.
