John Cena has always been potrayed as a larger-than-life superhero character in WWE for more than two decades. The Cenation Leader was a hero to millions and an inspiration who encouraged fans never to give up on their dreams. But he had another side to him in his personal life.
The fans got to witness Cena’s personal life and way of living when was featured on the reality TV series, Total Divas, and then Total Bellas. This came as Cena was in a relationship with the one of the members of the cast, Nikki Bella at the time.

Despite being together for five years and even coming close to being married, John Cena and Nikki Bella’s relationship ended. One major reason was Cena unwilling to have any children, while Nikki wanted to have one. However, there was an entire list of rules that governed Cena’s relationship with Nikki, with three of them being the most bizarre ones that possibly put the final nail in the coffin.
John Cena drew out an entire list of rules for his relationship with Nikki Bella

A few years into their relationship, Nikki Bella took a bold step to move in with John Cena in his lavish home in Tampa, Florida. However, what Nikki thought would be a happier journey as Cena’s live-in partner turned out to be a relationship governed by multiple rules. This was Cena’s first showing as the ultimate heel.
When Nikki Bella moved into his house, John Cena drew up a reported 75-page contract for her to sign. In total, the contract had 15 rules that Nikki had to obey and she was referred to as a ‘guest’ staying in Cena’s house. The rules included not having his own children, allowing filming when he wanted, not speaking ill about WWE, being highly strict about the cleanliness of his house, keeping his money his, not allowing personal photos, and more. While some might have seemed fair on John’s part, three of the rules were actually bizarre to know about.
One of those first rules was a ban on having pets in his house. Nikki Bella once brought a pet home. But John Cena quickly made Bella send it back, claiming that he did not have time or want to raise a pet, much like his aversion to never becoming a father. On the other hand, even pets also did not like Cena as once seen on an episode of Total Divas. It was then that Brie Bella’s dog, Josie bite the 16-time World Champion.

The second bizarre rule imposed by John Cena on Nikki Bella was tracking her calorie intake. He himself wanted to take charge of the same, but Bella quickly showed that she did not appreciate it. The last rule that possibly was a major part in ending their relationship was related to the Power of Attorney.
Nikki Bella wanted John Cena to be her power of attorney. This would have given Cena legal power to have a say in her business or legal matters and private affairs in case of any catastrophe. However, Cena refused to sign it and did not let Bella be his power of attorney too. All these rules possibly drained down the love they shared and marked the end of their relationship in 2018.
John Cena returned to RAW as a heel

While John Cena was the villain as perceived by many on reality TV, he became the same in WWE after turning heel at the 2025 Elimination Chamber PLE. For the first time since that night, the 16-time WWE Champion returned to RAW to address his actions.
The Cenation Leader launched a verbal barrage on the fans for the abusive treatment they made him endure for 25 years. Cena said that he no longer cared about the fans, and they meant nothing to him anymore. While Cena berated the audience in Belgium, they showered one of the loudest jeers on him and even sang goodbye to him.
Cena was also confronted and upstaged by his WrestleMania 41 opponent, Undisputed WWE Champion Cody Rhodes. Rhodes made it clear that he wanted to face ‘John Cena’ at WrestleMania, not the man whining in front of him. With the road to WrestleMania 41 getting more interesting, it will be exciting to see more shades of the heel John Cena moving forward.
