Blank debuted for the ECW brand as Kelly Kelly. Originally, she was to be named just 'Kelly', but her ring name was expanded to 'Kelly Kelly' by Vince McMahon. She made her debut on the first episode of the weekly television program on June 13, 2006, becoming the youngest Diva on the WWE roster. Her character, an exhibitionist, was introduced performing a striptease for the crowd. The next week, while performing another striptease, Kelly was interrupted by her on-screen boyfriend, Mike Knox, who came to the stage and covered her with a towel before dragging her backstage. Her stripping became a weekly segment known as "Kelly's Exposé" and usually followed the same routine; Kelly would dance and strip until she was interrupted by Knox who was upset by her exhibitionism and showing off her body to others. Knox began forcing Kelly to accompany him to ringside so he could keep an eye on her, making her his "de facto" valet. As a result, she found herself involved in the feud developing between Mike Knox and partner Test with Tommy Dreamer and his partner The Sandman, including being inadvertently hit with a cane by Sandman when Knox used her as a shield. She made her ECW in-ring debut on the August 22, 2006 episode of "ECW on Sci-Fi" in a losing effort as part of a six-person mixed tag team match which saw herself, Knox, and Test lose to Dreamer, Sandman and Torrie Wilson, in what was the last match of the feud.
