Zara Phillips broke the royal family's tradition of maintaining a stiff upper lip by greeting her uncle and cousin with hugs and kisses on day one of Royal Ascot.
The 33-year-old - who recently welcomed her first child with husband Mike Tindall - was all touchy-feely as she said hello to Prince Harry, Princess Anne, Camilla the Duchess of Cornwall and even her uncle and heir to the throne Prince Charles.
In a short black shift dress with chic white piping by Orla Kiely teamed a Philip Treacy hat, Diane von Furstenberg clutch and chic Gucci heels, the young royal had heads turning as she proved to be the life and soul of the party.
However, Zara wasn't the only one playing the rebel. Her rugby playing husband Mike was spotted doing his very best impression of Prince Harry, mocking his painstakingly practiced yet still rather awkward royal wave.
Not that Harry was bothered - he was later seen tipping his hat to his cousin and her hubby in playful acknowledgement of their good-humoured teasing. Oh what larks!
Unusually, the Tindalls arrived separately to the rest of the royal clan only meeting up with them in the Parade Ring.
Despite slightly breaking tradition, the couple did enjoy the first day of racing with The Queen, who was elegant in a sky blue Stewart Parvin coat and Trevor-Morgan hat.
