VIDEO : Kevin Costner on Bobbi Kristina: 'I Hope That God Opens Her Eyes and Lets Her Breathe'

Actor Kevin Costner was a close friend of Whitney Houston's since before the two shared the spotlight in the popular film The Bodyguard. So much so, he delivered an impassioned eulogy at the late-singer's funeral. And now, watching Houston's daughter Bobbi Kristina Brown hospitalized in a coma after being found unconscious in a bathtub -- just as her mother was nearly three years earlier -- Costner says he's hoping for a miracle. "I hope that God opens her eyes and lets her breathe and lets her brain work, and she gets a second chance," he told Nightline co-anchor Juju Chang in an interview last Friday.
