The former glamour model, 48, appeared in high spirits as she relaxed in a tiny black bikini while spending time with Wayne, 64, at a luxury villa on Wednesday.
In a video shared on social media, Katie leaned over Wayne as he lay back on a sunbed, using her body to block his view of the sun.
The pair then added a humorous voiceover from the Noughties comedy film White Chicks, turning the rare astronomical event into a joke between them.
As Katie leaned across him, Wayne dubbed the audio by saying: “Oh my god, what happened to the sun?”
Katie then pointed towards the eclipse and replied: “Easy, white chocolate, I wouldn’t want you to melt.”
Wayne appeared to embrace the joke, captioning the video: “Triple eclipse @katieprice.”
The light-hearted exchange came as Katie and Wayne joined millions of people who were keen to catch a glimpse of the rare celestial event.
The eclipse saw the moon gradually move across the face of the sun, covering as much as 96 per cent of it in some areas and creating a dramatic change in daylight conditions.
While the astronomical event attracted attention across the country, Katie appeared more interested in enjoying the occasion with friends and family during her Ibiza break.
The television personality had travelled to the Spanish party island earlier in the week with her son Harvey, 24, for some quality mother-and-son time.
The holiday has already included plenty of memorable moments, with Katie surprising Harvey with a special trip to Wayne’s famous day club O Beach.
The pair were treated to VIP bottle service during their visit, where Harvey appeared to thoroughly enjoy himself as he joined the celebrations.
In exclusive footage shared from the occasion, Katie and Harvey were seen being welcomed onto the stage in the middle of the club’s garden.
The crowd began chanting Harvey’s name as the mother and son stood together on stage.
Katie looked ready for the Ibiza party atmosphere in a lime green bikini and white kimono, while Harvey wore a red top with green shorts.
Harvey appeared delighted by the attention as he danced alongside the bottle girls, who held enormous orange boards spelling out his name.
He could be seen smiling broadly as he enjoyed the atmosphere, while Katie danced beside him and appeared equally pleased to see her son having such a good time.
The emotional reaction from the crowd appeared to make the occasion particularly memorable.
Wayne later praised Katie for bringing Harvey to O Beach and described seeing the crowd chant his name as one of the most special things he had ever witnessed.
His comments went beyond simply celebrating a night out and focused on the close relationship between Katie and her son.
Sharing a photograph of Katie and Harvey on Instagram, Wayne wrote a lengthy and emotional message dedicated to the reality star.
He acknowledged that the pair had experienced their share of difficult moments over the years, but said they had also continued to share a genuine desire to help other people.
Wayne wrote that he had seen “with my own eyes” how much Katie adored Harvey and how much her son adored her in return.
He also highlighted the small things Katie did for Harvey during their evening together.
According to Wayne, she was constantly making sure Harvey was comfortable, patting sweat from his head and checking that he was enjoying himself.
He also recalled Katie making sure the chef prepared Harvey’s favourite carbonara even though it was not originally on the menu.
For Wayne, those small gestures offered a different perspective on Katie away from the headlines and public attention that have surrounded her career for decades.
He suggested that people do not always get to see the mother behind the public persona, but that he had witnessed that side of her during their time together.
The evening eventually became about much more than the party itself.
When the crowd began chanting “Harvey! Harvey!”, Wayne said the atmosphere was unforgettable.
He described the love in the room as incredible and said the moment reminded him why creating experiences for other people was so meaningful.
Wayne’s message came after what had clearly been an emotional and enjoyable day for Katie and Harvey.
The pair’s trip to O Beach gave Harvey the opportunity to enjoy the kind of carefree celebration that Katie appeared keen to create for him.
Rather than simply spending the holiday relaxing by the pool, Katie made a point of taking her son somewhere she knew he could enjoy the music, entertainment and attention.
Their Ibiza trip has therefore provided a series of mother-and-son moments, with Katie appearing particularly focused on making the holiday memorable for Harvey.
Later that evening, the group continued the celebrations at a lavish villa.
Katie was pictured enjoying a barbecue with Harvey, Wayne and friends, keeping the relaxed holiday atmosphere going after their day at the beach club.
The gathering provided a quieter contrast to the huge crowd and energetic atmosphere at O Beach.
Katie’s appearance in Ibiza also comes as she continues to remain a familiar figure in British reality television and entertainment.
Known for her high-profile personal life and willingness to share aspects of her experiences publicly, she has frequently found herself at the centre of media attention.
However, Wayne’s message focused on a side of her that is less frequently highlighted.
His tribute centred on Katie’s role as a mother and the care she showed towards Harvey throughout their time together.
The relationship between Katie and Harvey has long been an important part of her public life.
Harvey, who is Katie’s eldest child, has regularly appeared alongside his mother at family events and in aspects of her television career.
Their bond has also been documented through the challenges they have faced together, making the Ibiza holiday an opportunity for Katie to focus on enjoying time with him.
The celebrations at O Beach appeared particularly meaningful because Harvey was placed at the centre of the occasion.
The crowd’s reaction gave him an opportunity to enjoy the attention in a positive and celebratory setting, while Katie was able to watch her son enjoy himself.
Wayne’s comments suggested that he was deeply moved by the scene.
He reflected on the obstacles and mistakes that he and Katie had experienced over the years, acknowledging that they had both had difficult periods.
Yet he chose to focus on what he described as the genuine connection they shared and their mutual desire to help others.
The message also appeared to underline Wayne’s belief that moments involving family and genuine affection are more important than public headlines.
His observation that “there are real people, real hearts and real love” behind the public image was particularly significant given Katie’s long history in the spotlight.
For Katie, the Ibiza break appears to have provided an opportunity to step away from the pressures of everyday life and enjoy time with her son.
From VIP celebrations at O Beach to a relaxed barbecue with friends, the trip has been filled with experiences designed around fun and family.
The eclipse added another unusual moment to the holiday.
Katie and Wayne’s playful video transformed a rare astronomical event into another opportunity for humour, with their White Chicks-inspired exchange providing a lighter side to the trip.
Wayne’s “triple eclipse” caption only added to the joke.
While the pair’s playful interaction attracted attention online, the wider story of Katie’s Ibiza trip has centred on her relationship with Harvey and the effort she has made to ensure he enjoys himself.
The emotional message from Wayne offered a glimpse into the personal moments behind the photographs and videos.
For all the glamour, parties and celebrity attention surrounding the holiday, the most memorable moment may ultimately have been much simpler: a mother making sure her son was comfortable, happy and included.
As the Ibiza getaway continues, Katie appears determined to enjoy every moment with Harvey.
And after an evening of barbecue, friends and laughter, the eclipse provided one more unusual memory from a holiday that has already given the mother and son plenty to celebrate.
