He's not like every other dad. He's a "cool dad." That's according to 12-year-old Casie Colson Baker, who walked the red carpet at the American Music Awards Sunday with her famous dad, Machine Gun Kelly. Often playfully holding her dad's hand, Casie told ET from the carpet that she was having a fun night with her "cool dad." Living up to the name, MGK was quick to win the first award of the night for best rock artist. 🔗 Visit our link in bio for more from the #AMAs 📸: Amy Sussman, @gettyimages
