Outspoken Katie and reality star Amy were filming together for new ITV2 game show Reality Bites, which is hosted by Stephen Mulhern.
After taking a selfie with Katie backstage, Amy was quick to tell her Twitter followers: "So I finally met the one and only @KTHopkins ... Can honestly say she is a really lovely lady #posers!!!"
In the photo, Amy and Katie can be seen pulling off their best pouts for the camera.
The snap even led Katie to admit that she needed to work on her pout. She replied: "@MissAmyChilds Thanks Amy - Lovely to meet you xx I need to practise my pout."
We're sure the pair had lots to talk about too, seeing as Amy competed in CBB in 2011, where she finished in fourth place.
Former Apprentice candidate Katie finished in second place on CBB latest series earlier this month, losing out to winner Katie Price.
Admitting she would stay in contact with Michelle Visage after striking up a friendship in the house, Katie said of her rivalry with Perez Hilton: "Every house needs a hero and a villain, and without Perez I would have been the villain."
