FameFlynet PicturesHappy Birthday, Knox and Vivienne Jolie-Pitt!
Five years ago today Angelina Jolie and Brad Pitt welcomed their youngest two children at a hospital in the South of France, bringing their brood from four to six.
It's been a whirlwind year for the adorable twins, who have been busy jet-setting around the world with their famous parents while living a life most adults would envy.
Most recently, Knox and Vivienne took a tour of Berlin with their movie-star mama and four siblings—11-year-old Maddox, 9-year-old Pax, 8-year-old Zahara and 7-year-old Shiloh—after celebrating Angie's 38th birthday with a fun-filled family dinner the night before.
It's also been a year full of personal growth for the Jolie-Pitts after Angie revealed she underwent a preventative double mastectomy to greatly reduce her risk of breast cancer.
The ever-supportive Brad shared how their entire family participated in the recovery process and did their part to help Angie heal.
Speaking with USA Today, the 49-year-old star explained how he and the kids "set up our own little post-op recovery that became pretty fun," admitting, "You make an adventure out of it."
"My most proudest thing is our family," the World War Z star gushed.
The twins have also become quite the style icons, developing their own fashion sense as they grow up in the spotlight.
And Angie and Brad have of course done their part to make sure their kids are well-educated, even toting their little ones to the Los Angeles Natural History Museum on Valentine's Day for an educational outing.
Sometime in the (hopefully!) near future, Knox and Viv will also witness their A-list parents tie the knot after the Brad and Angie finally got engaged last year due to their kids' demands.
"It is a promise for the future and their kids are very happy," Pitt's rep said of the engagement.
While no wedding date has been set, Brad confessed in the fall their kids are getting anxious for Angie to walk down the aisle.
"We're getting a lot of pressure from the kids," the father of six admitted. "We didn't realize how much it meant to them and then, in getting engaged, how much it also means to us."
No doubt, Knox and Vivienne will be the most adorable members of the wedding party.
Happy birthday, you two!
