Although after three boys mum Victoria long gushed about her desire for a daughter, Harper Beckham is clearly the apple of her daddy's eye. 

So there was little surprise when a smitten David look to Instagram earlier today to wish his precious princess a very happy fourth birthday. 

Choosing a snap of his girl as a newborn, he wrote: "Possibly my favourite picture of Harper of all time," he wrote. "Four beautiful years with the most amazing little girl… Happy birthday big girl."

With North West turning three, Penelope Kardashian Disick celebrating her third birthday, and Suri Cruise now the grand old age of nine, it's clear that the world's cutest celebrity offspring are growing up fast.
