A post shared by Katie Thurston (@thekatiethurston)Blake posted the same message alongside a color photo from the After The Final Rose special. Split speculation had been mounting, as they two had not been seen on each other's social media in over a month. Further, Katie's left hand was hidden or cropped out in pictures she posted over the past month. Katie, the star of season 17 of "The Bachelorette," got engaged to Blake on the season finale of the show, which aired on Aug.
