The 27-year-old singer said that right now they are spending time with Una Healy's daughter Aoife but would soon have children of their own, reported Femalefirst online.
"How many children would we like? As many as God will allow! I'm one of three, so maybe four. We both love kids and babysit my niece and nephew a lot. We've also been spending some time with baby Aoife, Una's daughter, and she's amazing," he said.
Humes, who has experienced an on-off relationship with Wiseman, also said that he has always known the 23-year-old beauty would make an amazing wife.
