John Cena and Nikki Bella have certainly had an up and down relationship on Total Divas season 2, but wedding fever is in the air on the WWE reality show. With many of their castmates and fellow coworkers in the WWE Universe getting married -- including Nikki's sister Brie Bella and WWE champion Daniel Bryan -- it makes sense that John and Nikki could be next in line to walk down the aisle. I am sure the E! Network would love that because if this past week is any indication, weddings = ratings.
