She'll replace Joan and Melissa Rivers, who have been the channels' mainstays for two years doing red-carpet hosting duties. Rinna will start at TV Guide Channel with this year's Emmy awards on Sept. 16.
The new TV Guide Channel will host the Emmys, Golden Globes, Oscars, Grammys, and the Screen Actors Guild Awards. Just like with the Rivers, Rinna will do fashion recaps of each event.
In addition to "Dancing," Rinna is also the host of Oxygen's "Tease," a reality hair-styling competition show.
