Nikki Bella is ''still shocked'' that John Cena wants to have kids.

The 'Total Divas' star - who is currently on a break with her fiance - was so surprised when John said he would be open to having children one day, even after he insisted it wouldn't happen.

Speaking in a preview for 'Total Bellas', she said: ''I still feel like I'm shocked about it. Even when he said it, and then everything happened so quick. Like, wedding's back on and we started all this planning so I didn't even let it soak in, like, 'Wait, John wants to have kids. Huge deal.'''

Meanwhile, Nikki previously insisted she and John are ''just friends'' right now.

She shared: ''Right now, we're just friends. We're working on each other and trying to work on us, and we talk every day. He is not only my best friend, but he truly is one of the best people I have ever met, and he has patience with me and he has really taught me a lot over the last few months, and I think one of those things is an inner strength that I thought I had, but didn't realise how strong I had it.

''It's giving us this time in life to see what we really want for the future. I know for some people, because of the media or what they read on social media, they look at this as a very negative thing, but ... I don't want to be someone who gets a divorce, or who has kids and gets a divorce. I truly want to walk down that aisle, I want to give my vows and I want this to be one time.

''I'm beyond grateful that I have this amazing man, who is staying by my side and helping me fight through those issues and helping me become just an even better person, and even stronger.''
