Witney Carson, the reigning champion of "Dancing With the Stars," says she'll deliver "three huge announcements" live on "Good Morning America" this coming Monday, Aug. 17, according to Parade. Insiders suggest the reveal could include a season 35 pro-celebrity pairing announcement, though ABC has not confirmed details. Four celebrities are already set for the new season, including "Summer House" star Ciara Miller, "Love Island" alum Maura Higgins, Savannah Bananas player Jackson Olson and "Jimmy Kimmel Live!" sidekick Guillermo Rodriguez.
