The royal couple — who are parents to 5-year-old daughterMiaand 1-year-oldLena Elizabeth— had the look of love at the Whatley Manor Gatcombe International Horse Trials at Gatcombe Park on Sunday.

Despite ascary fall off her horselast weekend, the Queen’s granddaughter, 38, competed in the event with her family there to cheer her on. At one point, Zara leaned into the car that Mike was driving for a sweet kiss.

The public display of affection comes as no surprise. While walking around the fairgrounds at the Festival of British Eventing at Gatcombe Park last summer, the couple were seensharing a kissas Zara held onto her husband’s backside!

Royal etiquette expertMyka Meier, founder and director ofBeaumont Etiquette, previously told PEOPLE that there areno formal rules on royal couples being affectionate in public— it’s at their own discretion.

“Senior members of the royal family would likely not be told how to interact or when they can or can not show PDA, and would be trusted to use their better judgement as to when it’s appropriate,” she explains. “The royals often adjust PDA to mirror the formality of the event they are attending. At a somber or more formal event, we are less likely to see PDA than at a casual event where it would be deemed more fitting.”
