Attending the launch of TOWIE star Ferne McCann's new clothing collaboration with Look Of The Day, Sam and Tiffany didn't seem too phased about being photographed together on arrival.
Probably because they weren't giving anything away...
While Sam rocked up in head-to-toe navy blue and an edgy pair of shades, Tiffany looked stylishly chic in a black crop top, suede khaki skirt and ankle boots.
Despite joining each other for the evening, the pair made sure to keep us guessing when it came to their relationship status, looking more like two friends than boyfriend and girlfriend.
But, even though their appearance in the capital didn't exactly cry 'we're back together again', we think we've rumbled the couple's romance as Chelsea boy Sam kind of gave the game away with his Instagram posts.
Taking to the photo-sharing app last night, Sam kept his followers updated with his evening out, revealing he was enjoying "date night".
While the reality star made sure not to reveal who exactly he had for company, it's a bit of a coincidence his romantic dinner snaps came the very same night he was pictured out with Tiff, no?
In one photo, Sam shared his candlelit dinner for two, telling fans: "Dinner date baby #goodtimes."
He then uploaded a shot of himself and his date clinking wine glasses, along with the hashtag "#goodlife".
Unlike her former flame, Tiffany was keeping her lips sealed on social media. Although, her outing with Sam comes after their MIC co-star James Dunmore shared a series of photobooth photos showing Sam and Tiff looking pretty cosy together.
James is dating Tiffany's older sister Lucy Watson.
Sam and Tiffany were first linked during the last series of Made In Chelsea. The pair struck up a cute romance, but it was shortlived after Sam admitted to Tiff he had kissed another girl.
Sam's drunken kiss came after he revealed he had let Fran Newman-Young sleep over in his bed, despite dating Tiffany at the time. Unimpressed with her beau's actions, Tiff then decided to call time on their relationship, telling Sam: "Now I know what type of person you are, and I don't need to associate myself with people like you."
Following their split, Louise Thompson's younger brother tweeted: "Couldn't be more of a mug..... I've let myself down. I'm going to learn from my mistakes and be the person I know I can be. #future."
Ahead of Made In Chelsea's current series, Reveal caught up with Sam to get the latest on him and Tiffany.
Recalling their break up, he said: "Everyone makes mistakes and I think it's part of life... I've grown up now. I can't see myself [cheating] again."
He then even teased all was not over for him and Tiff, telling us: "I thought at the end of last season there wasn't anyway back, but I think I've done pretty well to be fair. Hopefully I've shown her that I'm not a complete a**ehole and that I am actually quite nice still."
Sam is currently wooing MIC newcomer Millie Wilkinson on our screens, but maybe we should watch this space!
Made In Chelsea continues Monday 1 June at 9pm on E4.
