She’s gonna have a lot of explaining to do! There’s no doubt that Nikki Bella is madly in love with John Cena, but she gets caught in a super awkward situation on tonight’s episode of Total Bellas. Nikki’s mom Kathy Colace spots a mystery man wearing just a towel in Nikki’s new villa — which is a huge concern for Mama Bella. But is Nikki really cheating on John?

Season 2 of the Total Divas spin-off starts with a preposition from Nikki’s twin sister Brie Bella. Brie asks Nikki and John to temporarily move from Florida to Arizona in order to help her and her husband Daniel Bryan prepare for the upcoming birth of their daughter. Even though John can’t commit because of his demanding schedule, Nikki still agrees to do it and she rents a gorgeous villa for her temporary stay.

Nikki decides to give Kathy a tour of her new home via FaceTime, but as she walked toward a hallway, a dark-haired man wearing only a towel darts across. “Uh, who was that? Someone walked by, but the crew usually doesn’t walk by in like towels,” Kathy says, and Nikki tries to play it off.

But John has nothing to worry about because the mystery man turns out to be Nikki’s 28-year-old brother, JJ Garcia! The retired WWE superstar is helping JJ hide a very big secret from the rest of the Bella family after he revealed that he’s going through a rough patch in his marriage to his wife, Lauren “Lola” Garcia. In order to give each other space, JJ moves into Nikki’s villa — but he doesn’t want the rest of the family to know.

“Why do I have to be the only one who knows about this stupid a– secret? You f–king suck,” Nikki told her brother. “Mom probably thinks legit, I’m having an affair now with one of the crew members.”
