A Timeline of Nikki Bella and John Cena's Rollercoaster Relationship

Nikki and sister Brie also teased what's to come on Season 5 of "Total Bellas."

Nikki Bella says she would have some reservations about being a contestant on "Temptation Island" with her boyfriend Artem Chigvintsev.

While speaking with TooFab at the premiere party for the reality dating series, Nikki and her sister Brie Bella weighed in on how they think they would fare with their significant others on "Temptation Island."

"I have to say being in a new relationship, I don't know how I'd feel about being on 'Temptation Island,'" Nikki said. "I think I'd be timid and scared because there's so many beautiful, amazing people on there."

She continued, "Maybe Artem would make an amazing connection but I would have hope that he would be with me. But in the end, I'm like, 'Well, if you chose someone else, I guess we weren't meant to be.'"

Brie -- who has been married to WWE wrestler Daniel Bryan since 2014 -- expressed that she doesn't think her husband would be down to join the show in the first place. However, she seemed optimistic about how their marriage would fare on the series.

"If I asked Bryan to go on the show, he'd probably slap me," she told TooFab. "But I wouldn't, you know. I'll admit Bryan and I have been together for five years, and there's definitely times, especially having a child where you kind of think to yourself, 'Dang, marriage changes.'"

She added, "But I honestly feel like if I was with Bryan on 'Temptation Island,' he would never stray away. And I wouldn't stray away. But it would open up your eyes to kind of be like, you know what, there's other people out there, you gotta put your marriage on track."

The "Total Bellas" stars already know who they are rooting for this season of "Temptation Island," which premieres tonight.

"So Nicole is for Kate and David but I'm for -- not a couple -- I'm for two girls. The Ashleys," Brie said. "And I'm gonna call them Ashley squared. Because both of them I kinda really got teary-eyed for, because of the cheating and also one of them is super insecure. And I was just like, wait a second. They're both going to Temptation Island. Definitely one of the men is going to cheat with the other one. I want her to feel secure that her husband won't cheat. But it was crazy for me to watch. As a married woman, I'm like, 'Oh my gosh, the Ashleys! Like, kill me.'"

"Well, I'm for Kate and David," Nikki said. "I think they're going to make it. I just see this true love. And don't get me wrong, we all get tempted, [but] if you go to any island and have this Temptation Island -- I truly think that Kate and David are going to make it out strong. Sometimes, I feel like we need these temptations to know that we're super meant to be."

The former WWE divas also teased what's to come on Season 5 of "Total Bellas."

"We're really excited to film 'Total Bellas' Season 5. One, we have a new cast member, Artem," Nikki said of her beau and Brie added, "Everyone's excited to see Nikki's relationship unfold."

Brie and Bryan, who share 2-year-old daughter Birdie, said the new season will show the couple's pressure to have a second child.

"Like everyone keeps asking Bryan and I, 'When's baby number 2 coming?'" Brie said. "You get a really in-depth look at our lives and how freaking chaotic it would be."

She concluded, "I have to say 'Total Bellas' Season 5 is totally different than any other season you've ever seen."

"Temptation Island" Season 2 premieres Thursday night at 10 p.m. ET on USA.
