Brie also had a hard time writing Incomparable, particularly when it came to stories about her and Nikki's childhood.

"I think, people you love, you always want to protect them, but at the same time, you want to tell your story," Brie explained. "You want to tell people why you became the survivor of this story instead of the victim, and how [you] grew strength from it."

She admitted to losing "so much sleep" over the chapter that focuses on their parents, "but at the same time they were kids trying to raise kids."

On top of everything else, Nikki and Brie—along with their partners and family members—are watching the latest season of Total Bellas play out on TV. Nikki said she's never been more embarrassed of herself than she was after last week's episode, which chronicled a drunken fight between her and Artem.

"You guys I was so drunk," she told Erin and Scott as Brie teased her. "I didn't know that Artem kept sitting on the bench. Everyone thought I was ignoring him but I was so drunk. Oh god, it was just so embarrassing."

The spat between the couple was caused by what Artem saw as flirtatious behavior. They, of course, later made up.

"I mean, let's all be honest, make-up sex is the best sex," Nikki added. "For some reason it's passionate and angry and happy and just very emotional."
