Joining the boys at the Skiing with Heroes party, which was held at Kensington hotspot Bodo's Schloss, was former MIC star Hugo Taylor.
While Spencer, Proudlock and Hugo stayed together, Jamie was pictured hanging out with Pixie Lott's model boyfriend Oliver Cheshire.
Over on the E4 reality show, viewers have seen Jamie accuse Proudlock of being "disloyal", after finding out about Proudlock's plans to move out of their shared flat to find another place with co-star Stevie Johnson.
During Monday's episode (3 November), Jamie and Proudlock had a dispute at Will Colebrook's birthday party, with Jamie storming off after Proudlock refused to give him an apology.
However, after the episode, Jamie told fans that he and Proudlock are still the best of friends.
"We argue, we hate, we love and laugh with each other," Jamie tweeted. "This is why they call us a family. Hope you enjoyed the episode tonight #madeinchelsea."
McVitie's heir Jamie later shared a picture of the pair on Instagram, simply saying: "Always a brother."
Made In Chelsea airs every Monday at 9pm on E4.
