Olympic Alpine skier Bode Miller and his wife, Morgan, have been fighting for joint custody of Nate, his 9-month-old son with ex-Marine Sara McKenna.
“Nate is such a cool kid,” Miller tells Us. (He also has a 5-year-old daughter, Dace, from a previous relationship.) “He deserves every ounce of fight we have.”
He adds: “It’s been brutal. It’s so easy to get negative about it, but when you see him, everything shifts. I just want to make sure he has the opportunity to live a great life.”
Miller — who won Olympic gold at the 2010 Vancouver games — admits he’s made “mistakes,” but they have made him a better person. He’s currently training for the Sochi Olympic Games in 2014.
