The Lone Ranger actor, 30, revealed in September that the pair were expanding their family. "Ready to start the #torontointernationalfilmfestival festivities… All three of us!" he captioned an Instagram pic of himself rubbing Elizabeth's growing belly before a screening of his film Nocturnal Animals.

Armie and the bakery owner, 34, tied the knot in May 2010 after four years of dating. (They opened the Bird Bakery in San Antonio in 2012.)

In 2013, Elizabeth revealed how the Social Network star popped the question. "Armie really wanted to get married," she recalled to Town & Country at the time. "He sat me down and said, 'Look, we don’t have to do this. We could just go our own ways, and then one day you’ll be 40 and divorced and we’ll run into each other, and we’ll laugh and go out to dinner and have this same connection, and we’ll wonder why we wasted all of that time. Or we could just do it now and enjoy the ride.'"
