Kim Kardashian West braved the cold to strip down in the snow during a trip to Deer Valley, Utah, last year, wearing nothing but a fur bikini top, thong and boots for an impromptu photo shoot, she revealed with a #ThrowbackThursday post on her website/app.
Other snapshots from the vacation show the mother of two smiling in ski gear and snuggling with a sleepy Kanye West.
In this week's issue of PEOPLE, on stands Friday, sources close to the couple share insights into their high-profile marriage.
"You've never seen a more affectionate, doting husband," a source close to West says. "He idolizes her."
