HGTV is bringing the expressive comedian back to the network to host another round of “America’s Ugliest Houses” and “America’s Scariest Houses.” Just a glance at a video posted on both HGTV and Retta’s Instagram accounts gives fans a pretty good idea of exactly what to expect when “Scariest House in America” returns in September. Retta will travel the country finding the worst of the worst when it comes to ugly appearance, poor functionality and hideous design choices, ultimately crowning one house the “Ugliest House in America.”
