When will aspiring starlets learn not to let their partners make sex tapes? The latest celeb to get an unwelcome blast from her past is former Playboy pinup Kendra Wilkinson, now a happily married mom and star of her own reality show on E! Porn giant Vivid Entertainment has obtained a steamy tape of Kendra with a former boyfriend, and plans to distribute it within the next several weeks.

Kendra’s high-powered lawyer Yael E. Holtkamp has sent a “cease and desist” order to Vivid, adding: “The video is private and highly confidential taken for private use and not for public disclosure. Any exploitation of the video would be a gross violation of Miss Wilkinson’s constitutional and common law rights of privacy.” Sources claim Kendra made the video prior to her relationship with husband Hank Baskett with someone whom she trusted. Obviously, that trust was misplaced since the video wound up in the hands of Vivid.
