"I did and it's here," she said pointing to her left rib cage.
"We're those kind of people," Saldana noted before joking with the audience. "Oh, come on, be happy for us. He's had my face on his arm, so it's only fair."
The new ink was apparently two years in the making, according to Saldana, who married Perego in 2013.
"You want it to be in a place that's private, that you only show when you're, like, in a bathing suit," she shared. "We had this amazing artist, Mark Mahony, do the tattoo for us. And I've been wanting to get it for two years...but I finally got it. Because my husband has tattoos coming out of his ears, and every time we would go get a tattoo for me, he would, like, push me aside, and he would end up getting a brand new tattoo. So, two years later, I finally got the tattoo."
Last Friday, the Guardians of the Galaxy star captured a pre-tattoo snapshot at the Shamrock Social Club in Hollywood, California.
"#tattoo time with the great Mark Mahoney," she wrote.
Besides tattoos, Saldana dished on her and Perego's 2-year-old twin sons, Bowie and Cy.
"I wish I could say that it's great. It's f**king bananas," she quipped. "We're losing our s**t...They're just bananas and they're gangsters, and they're literally 'living by night' because they don't f**king sleep."
The native New Yorker went on to point out why having twins is hard work.
"Everybody romanticizes having twins -- and we love it, we don't regret it -- but let me just f**king tell you, the part that sucks about having twins is that you're catering to two people that are growing up at once at the same age, going through the same things, with different tempers. Like, opposite tempers," she explained. "And so, when they fight, they look like two dudes fighting over a girl at a bar."
