The actor and his wife, Renee, welcomed a daughter named Phoenix Monroe Morrison on 28 June (21)
In a statement issued to People.com, the proud parents wrote, "We Rise! Our family is now complete. Welcome, Phoenix Monroe!"
Phoenix is a little sister for the couple's three-year-old son Revel James Makai, but the Morrisons' journey to parenthood the second time around hasn't been easy.
Last year (20), the actor revealed the pair had "had a few miscarriages along the way," adding, "It's not fun stuff. But it has really opened us up to having the conversation and talking about things that are taboo or a little difficult to express. So I think it has really bonded us together a lot more."
The couple wed in 2014.
They conceived their first child during a trip to Hawaii. Renee told her online followers on Instagram, "We conceived this little nugget in Hawai'i, and I couldn't wait to spend a bit of my pregnancy back in the islands that fuel me like no other place on earth."
Two weeks ago before their second child was born, she posted her burgeoning baby bump along with a message to her unborn baby, "…I wait… patiently, knowing YOU have a plan. Trusting YOU are on your path. I surrender little one. To you. To the divine truth. I am ready when you are."
