The "Total Divas" and "Total Bellas" star also commented on how Cena's blossoming acting career plays a role in his WWE schedule.
"Not that it's a full time thing, but he has all these other opportunities and sometimes you just need to let your body heal as well," she said.
Fans speculated that Cena was retiring from in-ring action Sunday when after his match with Reigns, the 16-time world champion stood in the ring and emotionally looked on into the crowd as he received a standing ovation.
"What I like is last night I really felt like he passed the torch and he's found that one guy, Roman Reigns, that can really do what he does and just like what The Rock did for John and Stone Cold [Steve Austin] did for them and so last night, I think we witnessed the torch being passed on," Bella said of Cena losing.
Following No Mercy on Raw Talk, Cena said he was not retiring from the WWE but that his role has changed within the company.
"Regardless of whether I had outside opportunities or not, I'm 40 years old, and I have 15 years of track experience here in the WWE. And not at a normal level. At an elite level. And I don't know how [much] longer I can keep it up," he said.
"So I guess I'll be like a weird Batman character. When they shine the light, I'll come a-runnin'."
