A source told Daily Mail Australia: "Charlie keeps this part of his life very private. Some of his newer friends don't even know he has a son.
"I'm not surprised it hasn't been mentioned on the show, but it would be interesting to see what Ali [Oetjen] thinks about it all."
When Daily Mail approached Charlie, he reportedly said: "I can't comment on this."
According to the publication, Network Ten also denied to comment on Charlie's situation.
