HISTORY: CT and Diem provided the franchise with its most talked-about romance. After meeting on The Duel, bad boy CT supported Diem as she dealt with the side-effects of her chemotherapy. The couple would date on and off for years (some of them tumultuous), appearing on the show together and competing as a team during Battle of the Exes II. Unfortunately, Diem's ovarian cancer returned and she had to leave the show, with CT by her side. Diem passed away in November 2014 at the age of 32.
CT posted a touching tribute to Diem on his Instagram following her death, writing, "Our plan to be together forever hasn't changed... it's just going to take a little longer now. And I'm going to hold onto this ring for you till we are together again."
