The 35 year-old appeared on UK TV show This Morning with her husband Stephen Belafonte to promote their new reality show, It's A Scary World.
She said: "I'm not pregnant! But we are going to have kids at some point. Either next year or the year after."
Mel is mum to two daughters - Angel and Phoenix - from previous relationships, while Belafonte also has a daughter, Giselle.
Asked if they'd like a boy, Mel said: "That would be nice. But as long as the baby's healthy."
She then turned to her husband and said: "I want him or her to have your eyes, because they're really cute!"
