"It was super small but very romantic and beautiful," a source reveals to Us of the ceremony, which was attended by just a few close friends and relatives.
The New Jersey-born, New York-raised star and the Italian artist, both 34, were first linked in mid-May when they were spotted kissing after Saldana's Star Trek Into Darkness premiere in L.A. But an insider told Us in June that the newlyweds have "known each other for a long time." Another pal added, "They have great chemistry."
Saldana -- who had an on-again, off-again relationship with Bradley Cooper from 2011 to 2013 -- is loving life with Perego. "Zoe's thrilled to have someone she can enjoy life with!" an insider said.
The Guardians of the Galaxy actress was previously engaged to Keith Britton, CEO of My Fashion Database. They called it quits in November 2011 after 11 years together. Saldana spoke about her desire to settle down and start a family the next year, during an April 2012 appearance on Lifetime's The Conversation With Amanda de Cadenet.
"I'm Latin -- we start young, honey!" said the star, whose other film credits include Avatar, Colombiana, and Crossroads. "At 22 you're like, 'I just wanna hold something!' You want a little critter."
"I love the anxiety, the pressure of the loud room full of yapping kids. But I'm a kid myself," Saldana continued. "I get along very well with animals and children. I dig them, I get them. They make perfect sense to me. A child makes perfect sense to me. A child speaks more sense than an adult half of the time."
