James share custody of Scout with ex-partner Jessica Marais. The two split in 2015, and remain amicable in their co-parenting.
Recently, James shared a picture of himself taking Scout to school with Jessica.
‘I can’t believe Jess and I are already those parents standing at the school gate,’ the Packed To The Rafters star told TV Week.
Even more recently, the co-parents were spotted taking Scout out for a day at the beach with their current partners.
The blended family laughed and soaked up the sun!
We wish Scout a very happy birthday!
