Earlier this series, viewers watched as Tiffany dropped the bombshell that she had cheated on Sam while away in Hong Kong over the summer. Finding her confession too much to handle, Sam then ended their romance and things soon turned sour after he was accused of being unfaithful too - something he has strongly denied.
Now, however, it seems their rocky break up could all be water under the bridge as rumour has it the former flames have rekindled things.
Earlier this week, their co-star Binky Felstead seemed to let the cat out of the bag, after tagging Sam and Tiffany in an Instagram post that was captioned: "Date night."
They joined Binky and her boyfriend Josh JP Patterson (now the two have finally made things official!) and Sam was pictured with his arm around Tiffany.
Although, it seems the pair may want to keep things on the down low, as Binky has now deleted the photograph from her feed.
Maybe they're saving their reunion for the Christmas special?
Tiffany initially began dating Sam last year, but their relationship broke down after she found out he had cheated on her.
However, the pair then decided to give things another go and had seemed pretty smitten with each other. So much so, that Sam even proved his commitment to his co-star by getting her initials tattooed onto his bicep.
And while some questioned his inking, Sam said: "Don't regret a thanggggg @tiffany_w13."
Things haven't been plain sailing for the pair, though. This series, Sam prepared to tell Tiffany he loved her, but never managed to as she revealed she had kissed somebody else.
On hearing her confession, Sam told Tiff he was "done" with their romance, but later went back to his ex to hear her out.
She told him: "We had kissed on a night out when I was drunk and then after that I didn't really talk to him because I felt very awkward... We were friends, that's all there is to it."
At the time, Tiffany told Sam he wasn't innocent in their break up, admitting he had made her feel insecure. While away, Tiffany was sent pictures of her beau getting close to another girl on a night out. However, Sam had insisted nothing happened.
Struggling to move forward with Tiffany after their cheating drama, Sam told her: "Right now I don't want to be with you, I just don't know whether I can get over it... I don't think I can."
However, he was then accused of cheating on Tiffany. Millie Wilkinson told Tiff and her older sister Lucy she knew Sam had cheated.
He, meanwhile, stood his ground and insisted Millie wasn't telling the truth. Taking to Twitter, he wrote: "Doesn't matter who you are, when I'm right I'll never back down."
