Cena and Bella stunned the WWE Universe and world of showbiz when they announced the end of their engagement in April after a six-year relationship.
Some fans claimed the split is not real and was just put together to boost ratings for the new season of Total Bellas, a reality TV show that follows the every day life of Nikki and her twin sister Brie.
Bryan, however, stated that the WWE superstars have ended their relationship for real and the whole situation is very hard for both of them.
The four-time world champion told Gorilla Position: ”It is not my place to talk about their relationship because, like, I’ve had people say to me, like, ‘Oh, is it [the breakup] just for the show?’
“And I’d say, ‘No, it’s definitely not for the show. It’s a very real thing and it’s hard on both of them.’
“But any sort of comments like, I don’t necessarily think that if something were to happen with Brie and I, I wouldn’t want people very close to me saying, ‘Well, you know this?’ And it’s like, it’s their thing.
“Whatever they want to release to the public, they can do. Whatever they don’t want to release to the public, that’s not my place to say anything.”
Cena and Nikki got engaged last year at WrestleMania 33 in the middle of the ring after beating The Miz and Maryse in a Mixed Tag Team Match.
Rumours suggested the ex-Divas Champion broke up with the 16-time world champion because he didn’t want to have children.
However, the two-time Divas Champion dismissed the reports and claimed she pulled the plug because she had cold feet ahead of their wedding that was scheduled to take place on May 5 in Mexico.
