Earlier this month VB complained David's new hobby was "ruining her life" as he stayed up until 3am building the structure.

On one evening he only managed to cram in six hours sleep between his mega building session with daughter Harper, 8.

"It's 9:45 he was up till 3:30 on his castle," Victoria complained on Instagram.

David told her he still has 10 bags of bricks left as he was determined to complete the Harry Potter-themed toy.
