The Guardians of the Galaxy costars poked fun at the rampant pregnancy rumors during a stop at the New York Stock Exchange on Tuesday, posing sassily with their hands on their hips and their bellies jutting out.
The joke comes after Saldana, 36, emphasized her growing bump in tight dresses during the movie’s premiere and press tour. Though she hasn’t commented, sources confirm to PEOPLE that the actress is in fact expecting.
“She’s absolutely stunning and glowing,” one insider tells PEOPLE.
But Saldana, who secretly married husband Marco Perego last summer, is keeping the news to herself.
“I would like to thank all the f—ing media for invading our privacy,” she Tweeted on Thursday, later adding, “I would never blame my fans. You are all heaven sent!”
