The couple lost their second child in 2014 while they were still married and shared a joint poem titled Never to their Instagram accounts at the time.
"I'll never get to see your precious face, or whisper words to make you feel safe, I'll never get to hold you tight, when you can't sleep at night," read the poem.
"I'll never get to sing to you a sweet lullaby, to calm you down when you cry, I'll never get to fall asleep with you in my arms, all bundled in a blanket to keep you warm.
"I'll never get to hear you laugh and giggle, or see your little toes wiggle."
In the past, the Aussie actress said working Home And Away helped her to get through some of the hardest years of her life.
"I don't know if I would have been able to get through it all if it wasn't for this fantastic job," she told The Daily Telegraph in March.
"To be able to have something to come back to was just all I needed and I had this beautiful family here who supported me and loved me."
Ada is currently in a happy relationship with millionaire businessman Adam Rigby.
In an exclusive interview with WHO, the 42-year-old said her partner "makes me feel like I am the best thing that’s walked on this earth."
"He has that lovely ability to make you feel really special and loved and tells you all the time."
