The TV personality, 40, is taking her mind off her recent financial and family struggles with a wild week in Majorca, ahead of pal Melodie Pope's wedding.
Katie and her fellow hens jetted to Spain on Tuesday to ring in Melodie's final days as an unmarried woman.
Not holding back while away, Melodie went on to share a saucy snap of Katie enjoying a boozy bath on Wednesday, as the party got into full swing.
The image saw the mum-of-five throw her head back in laughter, as she posed naked amidst the bubbles with a pint glass of wine in hand.
Melodie, who has known Katie since their teenage years, took the opportunity to pay tribute to her long-time friend with an affectionate caption.
The hairdresser wrote: "Bestie of 26 years … loving our girly time! Fun times to us! #squad #girlsontour #pricey #time2laugh"
She followed up the post with a selfie of the girls at a cocktail-filled lunch the next day, despite their inevitably sore heads.
Posing in sunglasses to ease their hangovers, Melodie wrote beside the group snap: "Round two ….. time for cocktails #dingding #hangover #thirstythursday"
Katie has jetted abroad after narrowly avoiding bankruptcy, having been given three months to pay off her debts – reportedly worth £50,000 – last month.
Only adding to her woes, the star was left panicked last week when she could not get in touch with her kids Princess and Junior, while they were on holiday in Florida with their dad Peter Andre.
However, a pal later confirmed she had managed to make contact, after making a public plea to her singer ex, 45, on Twitter.
A friend told The Sun Online: “Katie was overjoyed to speak to them both. She’s a protective mum and was worried naturally."
