Nicodemou and husband Chrys Xipolitas are currently expecting their first child together, and reports had suggested that the pregnancy would be written into Home and Away with a baby storyline for Leah.
However, Nicodemou told the Herald Sun that producers have instead decided to hide her baby bump.
She confirmed: "[There'll be] lots of loose-fitting clothes, I think."
Nicodemou also admitted that she still has no idea whether she is having a boy or a girl.
"I am a bit of a control freak so it's strange, but we want to be surprised," she explained. "To tell you the truth, all I care about is having a healthy baby."
Home and Away airs weekdays at 1.15pm and 6pm on Channel 5 in the UK and weekdays at 7pm on Network Seven in Australia.
