Bradley Cooper says having children is the "next big step" in his life.
The 39-year-old actor, who has been dating 22-year-old British model Suki Waterhouse since February 2013, admits he is "looking forward" to having a family, but is disappointed his late father Charles, who died in 2011, won't be there to share the experience with him.
The 'American Hustle' star told the latest issue of Square Mile magazine: "I would love to be a father one day. I'm sorry my father won't be around to see his grandchildren, but he knows fatherhood was something I was looking forward to. That's my next big step in life."
While Bradley is smitten with Suki, he also has a special friendship with Jennifer Lawrence, who he is set to co-star alongside for the third time in their upcoming movie, 'Serena.'
He said: "We've had so much fun working together and I'm so proud of her success. She's one of the most down-to-earth and unpretentious individuals you could ever meet, and it's such a pleasure to spend time with her."
He added: "She's incredibly talented; she's one of those natural performers who are instinctively good at what they do."
The 'Hangover' heartthrob has been nominated for an Oscar twice in the last two years, but admits he used to worry he would never make it to the top and is still "hungry" for success.
He said: "There's this crushing anxiety you feel when you're not getting the parts you want, and you wonder if acting is your destiny.
"I struggled for a long time, and you never forget what you went through to finally make it. Even with the success I've had, I still fight for roles that I don't wind up getting, so there's still enough uncertainty to keep you hungry."
