Dakota Johnson and Antonio Banderas
The Mask of Zorro star was married to the Fifty Shades of Grey actress' mother Melanie Griffith for 20 years before they ultimately split in 2015, but that doesn't mean the stepfather and daughter's bond has been severed.
Johnson got emotional when she presented an award to Banderas at the 2019 Hollywood Film Awards.
"I come from a family of many a marriage and I got very lucky," Johnson, whose dad is actor Don Johnson, said. "I got a bonus dad who I realized that, over time, is actually one of the most influential people in my whole life," she said. "When I was six years old, my mother married a man who brought an unbelievably bright light and a whole new world of creativity and culture—and one remarkably magical little sister into our family."
