Sam Thompson and Tiffany Watson strip off in tonight's Made In Chelsea 2016 Christmas special.
It's the penultimate episode in the latest E4 series and a festive special.
Love is in the air in Chelsea and Lost Bois throw the ultimate festive party to celebrate.
Following their recent rows, Jamie Laing enlists the help of some reindeer and a sleigh to deliver a romantic gift to girlfriend Frankie Gaff.
Alex Mytton gets a surprise package in the form of Stephanie Pratt.
She tells him: "I spent a year having secret crush on you."
Meanwhile, Sam and Tiff take part in a naked Christmas card shoot, with pal Olivia Bentley behind the camera.
The couple get naked with only some baubles covering their modesty in front of Olivia as they take some festive snaps for cards to send to family and friends.
"I look like a scared little boy," Sam says of the results.
"Nothing says happy Christmas like you and and your girlfriend butt naked," Olivia concludes after Sam reveals plans to send the photos to his grandparents.
But it's not all jokes for the pair, with Sam asked to prove his commitment to Tiff. It leads to him getting down on one knee at the Christmas party...
Elsewhere, while the other couples in Chelsea are loved up for the holidays, Louise and Ryan are left questioning their relationship.
Made In Chelsea 2016 continues tonight on E4 at 9PM.
