MGK was put on this Earth to be a girl dad - and his birthday tribute to daughter Saga proves it. "1 🧁❤️🔥," the 35-year-old singer captioned a glimpse at his daughter's first year of life in an Instagram post on Wednesday, April 1. The baby's face was hidden in all the images. The musician shares Saga with Megan Fox and is also the father of 16-year-old daughter Casie with ex Emma Cannon.
