(AP Photo/TLC, Bryant Livingston) (Newser) – Despite the fact that he’s already being investigated for felony bigamy, polygamist Kody Brown of TLC’s Sister Wives has officially added a fourth wife to his family. Brown “married” Robyn Sullivan a few months ago, sources tell TMZ, and though there were no cameras at the actual ceremony, the reception will of course be featured on the reality show. Sullivan and her three children bring Brown’s total number of mouths to feed to 21. Click here for more on the bigamy investigation.
