The 36-year-old 'Guardians of the Galaxy' actress, who confirmed her pregnancy for the first time last month, is set to welcome two sons into the world with Perego in coming months, reported E! online.
"It's twin boys and Zoe is thrilled! Zoe has always wanted a boy," a source said.
Saldana announced she is pregnant with twins earlier this month when she was quizzed about on her plans for Halloween. Asked if she will be dressing up for the spooky celebration, which takes place on October 31, she rubbed her growing baby bump and said, "I might. I might need three costumes. I might have to make some adjustments, but it would be nice."
Saldana married Perego in June last year in a secret ceremony in London following a few months of dating.
