His disappearing act caused concern among viewers and shock for his family.
"It was a surprise he decided to take this week off when he will have the children the very next week during school holidays,"a family friend told Fairfax Media.
It's believed the children,Jackson,17,Ava,12,and River,10,will now spend the week with Stefanovic on the road while he works on theTodayshow.
The kids are usually full-time with Stefanovic's wife of 21 years,Cassandra Thorburn,46,whom he split from in July last year.
