Kim Zolciak finally discussed her hair/wig on “The Real Housewives of Atlanta” reunion special last night. We were excited to learn what the real deal is with that obviously fake hair. But sadly, Kim let us down because she really didn’t reveal anything. She said she had been very sick, lost weight, her hair fell out and a “doctor friend” told her she had cancer. She then admitted, as a total afterthought (like no one would hear), that she didn’t actually, have cancer, but had “other stuff going on.” Since we may never know what was “going on,” unless she writes a tell-all book, we’ve come up with some theories of our own. Check them out, and suggest your own, after the jump…
