Actor David Oyelowo also received his naturalization on Wednesday.
Zoe Saldana is feeling patriotic!
The Star Trek Beyond actress took to Instagram on Wednesday to celebrate her husband, Italian-born artist Marco Perego, as he received his United States citizenship.
"Marco has been dreaming about this moment for a long time," she wrote. "It was a process - as it should be, but we are finally here. We are aware it isn't as easy for many immigrants to obtain their citizenship, we say to them NEVER GIVE UP. Stay the course, America would not be what it is if not for the immigrants that come for better opportunities. We send love and good vibes to you all today."

In another photo, Saldana's husband poses with her mother, who smiles while waving a small American flag. In the background, Selma actor David Oyelowo can be seen sitting in the crowd with his wife.
"My mom has been a citizen since she was a young girl. Her mother arrived in NYC in 1961 and brought my mother from Dominican Republic when she was 10. My sisters and I are indebted to them both," Saldana shared. "Because of them, we are American women. So proud she is here supporting Marco! Oh, check out who is getting their naturalization today too... David Oyelowo and his wife! Congrats!"

Saldana posted one more image of her husband holding their twin sons, standing with a large American flag in front of them.
"God Bless the United States of America," she wrote, adding the hashtags "#fatherandsons" "#newuscitizen," and "#newcitizen."
The 38-year-old star secretly tied the knot with Perego in 2013 after a whirlwind courtship. One year later, she revealed that her husband had chosen to take her surname as his own, as she did his.
"I'm very happy that people are talking about [it]," Saldana told ET. "For men to be discriminated and picked on for wanting to take on their partner's name, for their masculinity to be put into question, I think it's disgusting. It shouldn't be that way."
"If my husband and I, what we're doing in our lives serves as an example then we're happy," she continued. "But we realized that by our fans writing to us that people have been doing this since the beginning of time. We're just the only ones that live in a public eye and it makes the news."
The couple welcomed twin boys, Cy and Bowie, in November 2014. In an interview with ET, Saldana joked about the lesson she hopes their children take from Perego's decision to take her name. Find out what she said in the player below.
