As she jetted off the exotic location, Katie was sure to update her many Instagram followers of her trip - first sharing some hilarious videos of Kieran Hayler being pulled along behind a speedboat.
And after a day of soaking up the sun, Katie and pals headed to a local cocktail bar, where the former glamour model stepped on in a gorgeous pink cami with matching nails.
Posing for several pictures throughout the evening, Katie enjoyed a birthday cake with her husband of two years Kieran, before more cocktails with two female companions.
Fans speculated over where the mum of five might be vacationing, as she uploaded a video of her and Kieran enjoying a helicopter ride, and a snap of a large vat of seafood paella.
But after partying for several days in sunnier climes, Katie returned home happy and relaxed, posting a snap of her new ‘bling’ converse trainers - that are covered in diamantes.
Obviously pleased to be reunited with her kids, Katie shared a video of baby Jett dancing along to the TV on Monday.
