The 'Joy' actor insists he has "stopping thinking about" being a sex symbol, but admits some days he thinks he's better looking than others.
He said: "I've stopped thinking about [people thinking I'm attractive].
"Sometimes I feel better than others. Yeah, I think it has a lot to do with feeling comfortable with yourself.
"And I know that I'm more comfortable with myself than I've ever been in my life, so maybe that makes me more attractive."
One person who thinks Bradley,40, is incredibly "sexy" is veteran TV presenter Barbara Walters.
Interviewing him for her '10 Most Fascinating People' special, the 86-year-old star told her guest: "I could just sit and stare at you but that would take too much time. But I find you very screwable."
She later added: "I think you're handsome, I think you're sexy."
Another of Barbara's Most Fascinating People this year is Amy Schumer, and the 'Burnt' actor has spoken of his admiration for her after she joked on 'Saturday Night Live' that she thought they were dating after having just one single conversation.
He has said: "She's amazing. I'm just a butt of a joke. I'm happy to be a part. She's hilarious."
