The proud new dad, 28, shared an intimate picture of himself holding his newborn tight.
"The most beautiful moment in my life," he emotionally wrote, before adding: "Welcome to the world Skyla Rose Morley. You will make it a better place. Mumma is doing very well and I am still speechless of her efforts! I can’t wait for the journey ahead."
The Home and Away alumni then followed up this post with little Skyla in cute Christmas-themed jumpsuit which read "Oh Deer".
"The world is your oyster and you will make it a better place. 1st Xmas ✅!!" Morely excitedly captioned the adorable snap.
The actor and his partner never confirmed when they began dating, however, there appears to be an engagement ring on Haggar's finger as per a sweet couple snap they shared on Facebook in the past.
The happy couple often shares loved-up snaps on social media, with Morley being open about having a special bond with Haggar's daughter and son from a previous relationship, whom he is a stepfather to.
Too sweet, a family of four now become a family of five!
