Jeremy Renner confirmed he is married - and flashed his wedding ring - this week
"I have tried to protect my family's privacy, my wife's privacy. I don't need her to get hammered with my life," Jeremy, 43, told Capitol File.
Asked outright whether he is a married man, he replied, "Yes."
On his decision to keep the news under wraps, Jeremy added, "It's annoying being followed when I'm with my family. It's not just me – everyone (in Hollywood) has to deal with that.
"I've been talked about a whole lot, because the less I put out there, the less people know, and it makes it interesting, I assume."
Jeremy was more open when it came to discussing his baby daughter, who was born in March 2013.

"It's the best thing I have ever done – doing it later on in life," he said. "By then I achieved a lot of things that I wanted to achieve; I'm so blessed for that. Now I can spend time with family.
"The only thing I think about when I'm not with my baby is, 'How do I get to my baby?' I need to get to her, and I'm very miserable when I don't see her.
"I really love being a father. The only that has changed is my perspective on things. I still work, probably even more. It used to be all for myself so I'm not old and broke. All these things I still do, but I do it now for the future of my baby, and if it gets in the way of her well-being, then I stop," the Hurt Locker star said.
"I can't wait for her to get older, but I really enjoy her now. She's the greatest. She's into her sticker phase... As a father, I'm going to make it very difficult for her to find a man."
