V1man was kind enough to pass information along today about the status of CT and Diem. The couple was "on" during The Duel, "off" by the subsequent reunion show and then supposedly "on" again for the duration of Gauntlet 3 filming.
Well now they are back off.
CT showed up at the Challenge Greatest Moments taping in NY (mistakenly also called the G3 reunion show) with a new GF in tow (kind of a skanky stripper/waitress type).
Some cast members say their relationship was all show which lends credibility to the claim that Diem is phony.
I can only imagine with Brooke and Ev sucking up all the available camera time with their "surprise" lesbian love show that CT and Diem decided to turn back "on" the relationship to make sure that they got their share.
Note: Looking at Diem's (friends) Myspace account, it has her relationship status listed as single which would seem to add conformation.
