There is already trouble in paradise on Honeymoon Island! In an exclusive sneak peek of the Married at First Sight spinoff, Kimber and Shannon argue over having a family.

When Shannon asked his match how she feels about having children, she responded, "We need to have this conversation, don't we? I really don't think I want kids. The way it changes your life, I don't think I ever want those changes."

Expert Dr. Jessica Griffin explained that she would not have matched them on Married at First Sight because of their "deeply different views on children."

When Shannon said, "But you don't know that you don't want them," she replied, "I was a stay at home mom for three years with the daughter of a guy I was engaged to."

Shannon told Kimber that it's different because her stepdaughter wasn't her own child.

"I came into her life when she was 11 months old. I was the only mom she ever knew. She really is my kid still," she said to Shannon.

She added in her confessional, "I am a stepmom to a little girl from a previous relationship. I potty-trained her, I was there when she took her first steps. Having that experience makes me more confident in saying I don't want to have a child that is mine."
