Is Prince George an Instagram Model? Well, no. But his mum (aka Kate Middleton, Duchess of Cambridge) could have fooled you with her personal snaps of the Prince that she released in honour of his 6th Birthday. TBH, we just can't believe he's six years old already. Taken in the garden of their home (that's the Kensington Palace to you and me), the photos show Prince George giggling and enjoying the great outdoors.
