John Cena and Nikki Bella get along very well and have similar tastes in humor. Cena and Nikki were shown on Total Bellas after the time when they got back together after they broke up and called off the wedding the first time.
Nikki started looking in her calendar and started to consider having their wedding on June 9th if it was a Saturday because it would be 6/9. Nikki commented how funny it would be if they changed the date of their wedding to 6/9 because it would fit their perverted senses of humor.
Then Cena commented on a possible theme saying, “come together on 6/9.” This would have been a hilarious thing for them to do but eventually, the two decided not to change the wedding date.
Of course, they eventually decided to cancel the wedding altogether but that’s a different story.
