Katie, 35, wore a cute little black dress to the Winter Carnival and was pictured cosying up to her hubby Kieran, 25, during their night at London's The Ivy.
The fundraiser was held by the Albert Kennedy Trust, which helps lesbian, gay, bisexual and trans people who are homeless, aged 16-24 and living in crisis.
During the evening, Katie uploaded the snap of herself and her husband to Twitter, telling fans: "Having fun with @kieran0322 at @AlbertKennedyTrust."
The Carnival even had a charity auction, hosted by none other than Blue and Big Reunion star Duncan James.
Meanwhile, proving her life isn't all about partying these days, mum-of-four Katie also tweeted a picture of herself and Kieran in bed together during the weekend.
Gone are her saucy days too by the looks of it, as the pair were sat up wearing matching black-framed glasses and Katie had her PJs on!
Alongside the photo, Katie joked: "Morning spec us out lol @kieran0322 is my Clark Kent!"
Wow, you guys certainly have plenty of specs appeal!
