The 30-year-old announced that the "Designated Survivor" actress was pregnant with his child in a humorous social media post on Friday, April 19. In the snap, Robbie can be seen clutching a faux baby bump while stood next to Italia and her real one.
"One of us is actually pregnant. @italiaricci," he joked in his caption, and Italia added in the comments section, "Probably the sober one with lopsided boobs cellulite and uncontrollable gas thanks babe."
The 32-year-old actress added the same picture on her accounts and jokingly wrote in the caption, "We will not take ridiculous portraits of this kid. We will not take ridiculous portraits of this kid. We will not take ridiculous portraits of this kid. We might take ridiculous portraits of this kid."
"We most certainly will," Robbie quipped in the comments section.
The couple got engaged in 2014, one month after they celebrated their six-year anniversary, and they got married in October 2016.
