The former X Factor contestant entered the compound last week with fiancée Chloe-Jasmine Whichello, and while the couple have decided not to have sex in the house, Stevi has made the decision to practically bare all.
Much to Chloe's shock, Stevi stepped out in a neon mankini, giving housemates an eyeful while sauntering throughout the house.
Only, Chloe's initial reaction was: "No Stevi. No!"
Big Brother *treated* us to a glimpse over on their live Twitter account. They said: "The mankini incident is still the talk of the house." We're not sure if it's part of a task, but judging from Chloe's response, it probably isn't.
When Stevi was in the X Factor house last year, he admitted to wearing a green mankini around the house to "stand out".
In fact, last year's X Factor winner Ben Haenow even told us that he avoided speaking to his girlfriend via FaceTime while in the house "because you never know if Stevi will be walking past in a mankini"!
Stevi isn't the first CBB housemate to wear a Borat-style mankini. In 2013, former TOWIE star Mario Falcone left a lasting impression as he donned a strikingly similar neon green mankini for a task.
CBB airs nightly on Channel 5.
