Winter is here! Game of Thrones star Sophie Turner and her singer fiancé Joe Jonas are planning on a winter wedding, a source exclusively tells Life & Style.

“It’s their favorite season, and they’re planning a winter wonderland theme,” a close source says, who adds that because of Joe’s tour dates and Sophie’s shooting schedule, the nuptials probably won’t happen until winter 2018. The couple hopes to tie the knot someplace “snowy,” the source adds, like Aspen, CO., or the French Alps. Reception guests will definitely be in for a chill.

“Joe has talked about having ice sculptures and a full bar made entirely of ice,” the source continues. “They’re both really excited about it.”
