Mike and Zara Tindall put on a very passionate display as they were seen snogging on the dancefloor while partying late into the night at the Isle of Wight festival on Friday.
The fun-loving pair left their three children at home as they enjoyed a trip to the island festival, where they were located in the VIP Blackstar area for much of the evening.
However, their late-night antics meant that the royal couple did not attend King Charles' first Trooping the Colour as monarch on Saturday.
Charles led the procession on horseback as he celebrated his first-ever birthday parade as King. It marked the first time in more than 30 years that a monarch had ridden at Trooping the Colour.
The King braved the sweltering temperatures as he wore full military uniform while riding his steed alongside son Prince William, sister Princess Anne and brother Prince Edward, who rode in the parade for the first time.
However, Zara and Mike - who have been married for 12 years - boogied away to hit song Common People when Britpop band Pulp took to the main stage on Friday night.
Earlier in the day the pair watched OneRepublic and Courteeners on the main stage.
At one point former Rugby World Cup winner Mike teased his wife by pouring a cup of water of her head as they basked in the warm temperatures.
One onlooker told The Sun : "They said it was their first time at the festival and they were looking forward to enjoying themselves and watching Pulp.
"They certainly seemed to. Zara didn’t stop dancing. They were messing around and laughing and joking.
"At one point Mike poured his drink over the top of her. It seemed like she enjoyed his rugby boy banter."
Zara, 42, did not seem to mind as she continued to sip on her cocktails and tried to get her own back by nicking her husband's hot dog.
Mike, 44, wore a Hawaiian shirt with a pair of dark shorts while keeping the sun out with a baseball cap. Zara - the granddaughter of the late Queen and niece to Charles - kept a casual look with denim shorts and a khaki jacket.
Following Pulp's set, the royal couple made their way to the Big Top stage when 1980s icons The Human League, who wrapped up Friday's events.
It was reported that Mike bought a bottle of alcohol before Zara and Mike eventually retired to bed.
