In Jeffrey, Jaden, Hiccup & Friends' Storm Adventures of My Little Pony: Friendship is Magic - A Canterlot Wedding, Cadence was kidnapped by Queen Chrysalis, and Queen Chrysalis disguised herself as the princess so that she could feed off of Shining Armor's love.

With her fiance's help, they both stopped Queen Chrysalis, and had their real wedding in the end, becoming Twilight's sister-in-law.
