In her statement, Zoe thanked their fans and explained their daughter Harper-Rose was their main priority.
Now, Alex has broken his silence on the split by sharing a touching tribute to his ex on Instagram.
Posting a picture of their 'wedding' from MAFS, Alex wrote in his caption: "Zoe and I both went into this experiment with open minds and really hoping to find a partner to share our lives with. We are so fortunate and thankful that we were matched together and have shared many great experiences over the last four years.
"We share the most important thing in both of our lives Harper Rose and will continue to love her and be the best parents possible. Although Zoe and I have separated our relationship is civil. Thank you to our friends and followers for your continuing support."
