Kate Middleton wore a $69 Zara dress for a surprise family outing

Prince George will be king someday, but that doesn't make him immune to a little teasing from his older cousin, Savannah Phillips. Crowds assembled outside the palace lawns to watch the Trooping the Colour ceremony which saw several musicians, about a 1,000 soldiers march together and a stunning flypast by the Royal Air Force.

Twitter account Elegantroyals added: 'This was the only disappointing thing about today's polo match.

The Duchess of Cambridge surprised royal fans when she took Prince George and Princess Charlotte to watch dad Prince William compete for the Maserati Royal Charity Polo Trophy at the Beaufort Polo Club on Sunday.

Adrina Price commented: 'Sad to see George playing with a gun when the whole country has a gun/knife crime situation.

Other people called for the critics to understand that there is a big jump between playing with a toy gun and growing up to use a real gun.

While Charlotte left us gushing over how adorable she looked even while crying, after she fell from the bench on the Buckingham Palace's balcony, one can not ignore Prince George's naughty antics. Sadly the royals will never change'.

Both mom and kids looked happy to be relaxing in the park the day after the annual Trooping the Color parade on Saturday.

The charity match will help raise funds and awareness for two charities, the Royal Marsden, which the Duke supports as president, and Centrepoint, of which he is patron.

But photos immediately after show Kate was actually running to greet England polo player Malcolm Borwick, who appeared to be beckoning her from beside the white marquees a few metres from the grass bank.

Tickets cost up to £150 a head for the event, described by organisers as a "special day out" and featuring rural demonstrations, a tented "shopping village" and traditional funfair.
