Bella and Cena shocked the world of wrestling and showbiz when they ended their six-year relationship last year shortly before their scheduled wedding date.
Rumours suggested that the two-time women’s champion pulled the plug because The Leader of the Cenation didn’t want to have children.
The ex-Divas Champion shot down the speculation and claimed she broke up with The Champ because she wasn’t willing to sacrifice her career and ambitions for an engagement that required one of them to stop working.
The former celebrity couple seem to have moved on as Cena has been spotted dating Avigilon product manager Shay Shariatzadeh and Bella started going out with former Dancing With the Stars partner Artem Chigvintsev.
But a source close to the Total Bellas star told HollywoodLife that it would break her heart if the 16-time world champion had a baby with another woman.
The source claimed: “Nikki would be heartbroken and crushed if John ended up having a baby with someone other than her as that’s truly the only reason they broke up.
“She always wanted to have a baby with John and the thought of that happening with a new woman is really hard to digest, but of course it’s crossed her mind.
“She tried everything to make their relationship work and sacrificed as much as she could, but at the end of the day, that was one thing she decided she just couldn’t go forward with.
“She loves being an auntie and truly can’t wait to have her own children.
“She’s so maternal and will be the best mom but she’s not putting any pressure on herself.”
Bella admitted that she was shocked when she found out about Cena’s new relationship but wishes him all the best.
The 35-year-old WWE star even playfully warned his new woman that if she breaks his heart she will hit her with her finishing move the Rack Attack.
She said: “”Let me tell you, [if] she breaks his heart, wow…
“I will Rack Attack her in a heartbeat.
“Still protective of that man”.
