The actor, who recently came third on Channel 5's Celebrity Big Brother, said that the pair's bond will be strengthened following the arrival of their baby daughter Nell.
Moloney told PA: "I think it will make them become more united. It gives them a different realm to focus on and they'll just grow more as a couple, I think."
He continued: "Toadie just loves taking Nell everywhere - he doesn't want to be apart from her. He just loves her to bits.
"I've loved having a little baby in to play with again."
UK viewers have seen a tough time for Sonya (Eve Morey) this week as she suffered serious health complications following Nell's birth.
Moloney joked: "It's quite nice when Eve is in a coma, normally she upstages me just by opening her mouth, which is quite good! It's nice when she's not saying anything!"
