The little stars are becoming famous in their own right. They even have a website dedicated to them which has been created by their parents under their joint nickname "dembabies".
Nick recently posted a string of cute snaps of the two on his Twitter page. One of them shows his son wearing sunglasses, a chain and a toy microphone.
Another shows his gorgeous little girl reading a children's book entitled My Mother Is Mine.
It's a little princess!
