The 'Aloha' star, who is dating Russian model Irina Shayk, claims he has no regrets, but wishes he had been less anxious about being successful in the past.

The 40-year-old actor said "I would probably tell myself not to worry so much. But I wouldn't change anything, gosh, no."

The heartthrob's co-star Emma Stone, 26, also wishes she had been more relaxed.

She said: "I'd tell myself to relax a bit around the edges when I took things very, very seriously."

Bradley told PEOPLE: "We're two people who have been so blessed, it's crazy. We get to do what we do and love, and work with the people that we get to work with. And I get to work with her."

The 'American Sniper' star is close friends with Emma in real life and confessed she makes him laugh more than anyone else.

He said: "We laughed so hard during the whole movie. We like to see comedy in everything, at the most dramatic possible moments. I laugh around her more than with anybody else."
