It was "Guilty Pleasures Week" on DWTS, so the WWE Diva and pro-partner Artem Chigvintsev performed a Fifty Shades of Grey-themed Viennese waltz, set to Rihanna's "Love on the Brain," and the number set the dance floor on fire.
Following their dance -- in which Bella showed off her flawless physique in a sheer, sexy black lingerie-inspired ensemble -- the pair were joined by Cena, who was welcomed to the stage by host Tom Bergeron.
"I thought it was probably a good idea to just get you out here to give your comments first," Bergeron said, laughing.
For their efforts, Bella and Chigvintsev earned a 21 out of 30 -- a score shared by four other couples including Derek Fisher and Sharna Burgess, Nick Lachey and Peta Murgatroyd, Terrell Owens and Cheryl Burke, and Frankie Munitz and Witney Carson.
ET caught up with Bella during rehearsals this week, where she opened up about performing a dance inspired by the erotic novels and admitted that she and Cena have their very own red room.
"[John] really built me a beautiful red room," she explained. "The walls are like beautiful red velvet walls. Actually, the door going into it looks like a door from a castle. It's pretty insane. It has fur rugs, candles, chandelier. A lot of drawers."
Check out the video below to hear more about her steamy relationship, as well as her other guilty pleasure: cheesy romance novels.
Dancing With the Stars returns next Monday at 8 p.m. ET/PT on ABC.
