Chad and his fiancée, McKenzie, plan to tie the knot in September.
McKenzie says she always dreamed her twin sister, Brittanie, would be her maid of honor, but that is no longer happening because, just a few weeks ago, McKenzie told her twin to stay away from the wedding because she claims her sister is a manipulative drug addict who is currently not fit to attend the wedding.
She also says Chad told her to choose between her twin sister and him!
Brittanie says she is devastated and will do whatever it takes to get clean.
