Princess Eugenie has shared a heartwarming social media post dedicated to her young son Ernest as he marked his third birthday - but there was no sign of Andrew Mountbatten Windsor or Sarah Ferguson. Eugenie, 36, was pictured planting a big kiss on her little boy's cheek, alongside a series of other snaps of 'Ernie' kicking a football. One showed him holding hands with an older boy believed to be his big brother August, 5, and another of him playing with balloons. Eugenie accompanied the post
