The 38-year-old former glamour model couldn't help but beam with pride as she watched her younger sibling Sophie pick up her degree in history from her university but, although it was a day of celebration, there was no doubt some tension in the air as Derrick Pountney was invited along to the special event and rubbed shoulders with her spouse Kieran Hayler, two years after the handsome builder was caught having sex with businessman's former wife of 10 years.
Taking to her Instagram account, the blonde bombshell uploaded a photograph of herself and Derrick, who was married to Katie's ex-best friend Jane for 16 years until her infidelity was revealed, beaming down the camera.
She captioned the picture: "My and d Besty Derrick Pountney (sic)"
However, despite the presumably awkwardness between Derrick and Kieran at the event, Katie didn't let the animosity ruin her sister's special day and continued to upload videos and pictures of Sophie collecting her degree, along with images of herself and various family members including her parents and aunt.
Alongside a photo of Sophie, she wrote: "My clever geeky sister @sophie_pricey she has got her degree in History #brainy #geek (sic)," followed by four graduation hats and a heart emoji.
Katie was left heartbroken in 2014 when she found out Kieran, whom she'd only been married to for less than a year at the time, had been having an affair with her close friend Jane, who was her bridesmaid, for 10 months behind her back.
The former 'Loose Women' panelist revealed her spouse's deceitful behaviour on her Twitter account, but Derrick - who has a son and a daughter with Jane - initially claimed the situation had been blown out of proportion.
He said at the time: "We are good friends of Katie and Kieran's and have been good friends of Katie for a good 20 years. A lot of this drama has been a storm in a teacup and there's a lot of misunderstandings to sort out. This 'affair' has not really happened like it has been portrayed. I've known about it for about four weeks myself."
However, Derrick later had a change of heart and filed for divorce from Jane after he learnt the extent of her affair.
Katie, who was pregnant with the couple's second child Bunny at the time, decided to give Kieran - whom she married in 2013 - another chance after she caught him out and stood by him while he was treated for sex addiction.
She said: "He wasn't allowed [sex] for ages, because of the therapy."
Katie and Kieran have son Jett, three, as well as two-year-old Bunny together, and are hoping to adopt in the future.
The reality TV star also has son Harvey, 14, from her relationship with Dwight Yorke and Junior, 11, and Princess, nine, with her first husband Peter Andre, whom she divorced in 2009 following four years of marriage.
