In a clip from next Monday's episode, Georgia 'Toff' Toffolo unveils some new photos of Sam from a night out which leads Mark-Francis Vandelli and Victoria Baker-Harber to question his loyalty.
Before showing Mark, Victoria and Jess Woodley the snaps of Sam, Toff explains that he was "well behaved", but says their "naughty night out descended into anarchy".
When Toff says the pictures are already circulating on social media, Victoria looks at them, calling it "trashy".
The photos in question, show Sam with his jeans halfway down and his bottom on display, with a girl seemingly hitting his behind. Another picture shows him posing with other partygoers.
"Eww. He makes me feel a bit sick," Victoria says. "I would break up with him in a flash."
Toff adds: "Everyone was very well behaved but I'm just worried that Tiffany will be upset by those photos."
Will Tiff find out about the photos? And how will she react?
Sam and Tiff are just getting back on track after hitting a rocky patch at the end of the last series. At the start of the current 11th series, showing that he and Tiff are stronger than ever, Sam declared: "I'm in love man!"
