Earlier today, Sam posted a close-up selfie of the pair soaking up the sunshine in the fancy French town and added the caption: "Hello from Cannes".
Err, yeah. Not jealous at all, guys.
And judging by photos, the Made In Chelsea pair look blissfully happy in each other's company. Smiling to the camera, Tiffany looked pretty wearing a blue top and her blonde locks loose. Meanwhile, Sam posed in his Ray Ban shades and went smart in a blue shirt.
Don't they look like the perfect couple?!
Clearly loving life, Sam also uploaded a photo of himself and co-star Jamie Laing on a boat, mid-conversation. Explaining the image, Sam wrote: "When you're arguing about who takes the first backflip off the diving board!". Tough times for these two, right?
The Made In Chelsea gang have headed over to the French Riviera for the summer and seem to be having a fabulous time. Well, it would be hard not to. In previous years the cast have headed over to the likes of New York and LA but this time they'll be spending time in glam Cannes.
And the best news of all? Former star Francis Boulle is attending - yes! After departing the show in 2013, the hilarious chap is set to be return to our screens for plenty of partying and drama with the rest of the Chelsea lot.
Sam continued with the stream of envy-inducing snaps by posting a photo of some of the cast. Gathered around a table on the beach, we spotted Ollie Locke, Jamie Laing, Alex Mytton, Georgia Toff - as well as newbies Frankie Gaff and Matt Draper.
We can't wait for this to start, bring on the drama!
