But it seems there’s one person who may not have quite got the memo, and that’s Swift’s ex, actor Tom Hiddleston, who was taken aback when it cropped up in an interview this week. He appeared on Heart Radio alongside Life of Chuck co-star Karen Gillan, where they were asked how they ‘spend a night’.

Swift spoke about her love of numerology during the show, and fans linked her comment about having thoughts of sourdough “60 percent of the time” to next year’s Super Bowl since it is the NFL’s 60th ever. The game will also take place in Levi’s Stadium, home to the San Francisco 49ers whose mascot is notably Sourdough Sam.
