Zoë Saldana Welcomes Twin Sons Cy Aridio and Bowie Ezio

Zoë Saldana‘s baby bliss is out of this world.

The Guardians of the Galaxy star has welcomed twin sons with her husband, artist Marco Perego, PEOPLE confirms.

“Cy Aridio and Bowie Ezio Perego-Saldana were born Thursday, Nov. 27 in Los Angeles,” Saldana’s rep tells PEOPLE. “Mother and sons are happy and healthy.”

“Our boys Cy and Bowie are finally here. Marco and I wanted to thank you for your beautiful wishes and for your patience,” the actress Tweeted Friday. “Happy #2015! Starting our New Year with a full house.”

Despite rumors that she was expecting, Saldana, 36, stayed mum throughout the beginning of her pregnancy — until she was photographed bumping bellies with costar Chris Pratt during their July press tour.

But showing off her burgeoning belly in a white dress while posing next to Pratt was only the start to her stunning series of bump-friendly frocks.

“Whatever it is you’re feeling internally, doesn’t mean that you have to look it,” Saldana, who refused to let pregnancy symptoms put a damper on her style, told PEOPLE. “Make an effort and look beautiful because it’s a beautiful time.”

In October, a source confirmed to PEOPLE that Saldana and Perego — who wed in summer 2013 — would be welcoming twin boys.

“She is beside herself happy over it all,” the source said.
