Cooper discussed how his sobriety helped him in his movie 'A Star is Born' alongside Lady Gaga
Bradley Cooper is being transparent about the parameters to parenthood - divulging what he hopes he can keep from his young daughter, Lea.
"You learn from your - the predecessor's mistakes - and I'll make tons that hopefully Lea will learn from," Cooper shared during an episode of National Geographic’s "Running Wild with Bear Grylls: The Challenge." Along with adventurer Grylls, Cooper explored the Wyoming Basin and hung on the side of a cliff.
"And then, making it and being rigorous with myself to grow. To help unburden her with any of my bulls---," he added of parenting. Cooper shares Lea, 6, with his ex Irina Shayk.
When Grylls suggested this was the best thing Cooper could do for his daughter, "The Hangover" actor added it was also something he actively does for himself.
