Two-time Oscar nominee Jeremy Renner secretly married Sonni Pacheco, the mother of his daughter, E! News reported Wednesday. He showed off his wedding band Tuesday during the screening of “Kill The Messenger.”

Pacheco, 23, is a Canadian actress who is known for 2009’s “American Pie Presents: The Book of Love” and 2012’s “The Wingman,” the Internet Movie Database wrote. The couple met on the set of “Mission: Impossible--Ghost Protocol,” Radar Online said.

They apparently didn’t have the steadiest relationship in the past. When it was revealed Pacheco was pregnant, the couple had already called it quits, but Pacheco continued to live at his Los Angeles home. “He realizes it’s unconventional to have his baby mama, an ex-girlfriend, living with him and his roommate, but he just doesn’t care,” a source told Radar Online.

But the drama seems to be in the past. Renner revealed the happy news when a reporter noticed his wedding band and blatantly asked if he was married. So why keep it a secret?

“I have tried to protect my family's privacy, my wife's privacy. I don't need her to get hammered with my life," he told the magazine Capitol File, according to E! News.

"It's annoying being followed when I'm with my family," the “Avengers: Age of Ultron” actor added. "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."

Becoming a father refocused his priorities, the “Hurt Locker” star told the mag, according to People. “It's the best thing I have ever done-- doing it later on in life," he said about being a father to daughter Ava Berlin, now 17 months. "By then I achieved a lot of things that I wanted to achieve; I'm so blessed for that. Now I can really spend time with the family."

Even though he enjoys his work, family comes first for the star. "The only thing that has changed is my perspective on things," he said of fatherhood. "I still work, probably even more. It used to be 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."
