John Cena

WWE power couple John Cena and Nikki Bella spooked fans by swapping places for Halloween.

The duo dressed up as each other, and instead of saying, 'Trick-or-treat,' the couple reenacted each other's signature entrances. The results are something you cannot un-see.

The couple has reportedly been together since 2012, but this is the first-known time they have dressed as each other.
