The 17-year-old looked beautiful, wearing a bright red dress and strappy high heels. Fans were blown away by the fact the teen was of prom age already and commented: "She’s beyond gorgeous. You done good dad. Time to fly. It's a huge transition. More for us than them," and another added: "They're so grown now."

Many others marveled at how grown up his 'baby' looked and said it was a "gorgeous moment" captured. 

Both girls have also carved out careers in the modeling world and have strut their stuff on the catwalk for swimsuit campaigns and are clearly growing up to be strong, independent and confident young women.
