Questions range from how they take their coffee, to what they wanted to be when they were children, to who would be their ultimate Outlander guest star.

While crowning a winner, we also learned who is a spoilsport when it comes to karaoke (spoiler alert: two out of the three) and which actress was on the poster Catriona got Sam for his birthday (hint: she’s in a blockbuster hitting theaters this week).
