The Bella Twins might be retired from in-ring competition, but they still fight hard! On the upcoming Season 2 premiere of the Total Divas spin-off Total Bellas, Nikki Bella and Brie Bella get into a sisterly spat over the importance of family — and it's all because of Nikki's man, John Cena.

Nikki and Brie are gearing up to launch a handful of new businesses — which includes their new clothing line Birdiebee and a wine brand called Belle Radici — all while Brie was preparing to welcome her firstborn daughter with her husband, SmackDown Live General Manager Daniel Bryan. Nikki asked John to move with her to Phoenix to help Brie with their product launch and the birth of Brie's baby girl — and he initially said yes, but ultimately went back on his word. Brie is known to be as blunt as possible with her sister. Watch the video below to find out why Brie said she doesn't feel like John is part of their family!

Brie always gave her sister a hard time about John in the past, especially since he was previously adamant about never wanting to get married again after his divorce. But John changed his mind and he proposed to Nikki during an epic moment at Wrestlemania 33 back in April — and she said yes, of course! Now Nikki is slowly starting to plan their upcoming wedding, and she dished about how far along she got in the planning process.

"So, I do have a date and I found a dress, so now I'm just trying to work on everything in between," the 33-year-old told Life & Style. "I just want to enjoy being engaged — you can be married forever, so I'm just enjoying being a fiancée. I'm going to really take my time."
