Having kids has always been in the back of Nikki Bella's mind, and therefore, a constant issue between her and her ex John Cena because he never wanted them. However, it wasn't until Brie Bella gave birth to her daughter, Birdie, that solidified Nikki's decision to definitely want little ones of her own. Watch the video above to see the Bella twins talk about motherhood, their careers, and getting back into the ring!

"I guess I never experienced unconditional love before and Birdie was my first," Nikki exclusively told Life & Style. "To feel that unconditional love that you would do anything for this human being in the drop of a dime, even when they're fussy or upset, you still love them so much. That's what made me start to realize I really want to experience this."

Nikki's desire to have children has always been a theme on the Total Divas spin-off show, Total Bellas. But because John wasn't exactly keen on having kids and raising a family of his own, they decided to call of their wedding.

During a promo for Season 3, John told Nikki, with tears streaming down her face, "I will never force you not to be a mom." She replied, "I thought I could really sacrifice that and I just can't." Then John told her, "I'm not sure that we should go through with this."

The pair announced their decision to call off their engagement on April 15. "After much contemplation and six years of being together Nikki Bella and John Cena announced today their decision to separate as a couple," a statement read on Instagram. "While this decision was a difficult one, we continue to have a great deal of love and respect for one another. We ask that you respect our privacy during this time in our lives."

While the news devastated fans of the couple, Nikki and John have since given the world slight hope that they could rekindle their romance one day. During a recent Today Show appearance, John made it very clear that he didn't want to be with anyone else. "I had my heart broken out of nowhere," John explained. "I love her, I want to be with her, I want to make her my wife, I want to be the father of her children, I just want us to work."

Nikki was rightfully shocked by her ex's confession as his attitude has seemingly changed about having children since their split. "Wow," she told Extra. "Well, I'm speechless. That's crazy."
