Pretty Little Liars’ Troian Bellisario Expecting Baby No. 3

"We don’t know your name yet. We don’t know your gender. We don’t know what your smile looks like or what your first laugh will do to our hearts," he wrote Nov. 4. "We don’t what will make you laugh or cry or what food you will fall in love with first. We don’t know what will scare you or how you’ll learn to overcome it. We don’t know what kind of music will make you want to move or what kind of clothes you’ll reach for when your arms are strong enough to grab them." The Wayward actor further noted that while he and Troian may be experienced parents, they are still looking forward to the happy surprises that inevitably come with a new baby, including the "gymnastics our hearts will do when we get to hold you for the first time." "We’ve been here before but we’ve never been here with you and so we really know nothing at all. Almost nothing," Patrick added. "What we do know is that we have an infinite supply of love waiting for you. Love, laughter, tears, dance parties, lullabies and lessons. We’ll show you some stuff but you will teach us everything else. We don’t know much but we know there is nothing we want to be more than your parents."
