When RehabAddict first started (possibly on the DIY channel), Nicole launched a Facebook page somewhere shortly after. There were hardly any people following her at that time. Just after New Years, she posted a pic of herself in a slinky, silky almost slip-looking dress that went to the floor, and said it was her wedding dress and that she'd just been married. In fact, she wrote a little paragraph about how she was so busy, she just bought the first dress she came to that fit, and how her and her groom had a very simple wedding with only close friends.
Because I'm nosy, I Googled her name and found dozens of photos of her and a very handsome man attending many social events together. I assumed that was the man she'd married. A few weeks later, the Facebook post was deleted and there was never any public mention of her being married. Now, Googling her name won't even turn up photos of her with the handsome man from that time.
A few weeks ago I stumbled across her Facebook timeline again, and she had a lengthy rant on the trouble her family was causing her, the infighting, backstabbing, fame-seeking family members, and so forth. That post now seems to be gone also.
Edited to Add (ETA): Her parents were featured in previous episodes, but she does not seem to mention them AT ALL now in interviews, FB posts, etc. It's all about her Grandpa.
She seems like a nice lady, with a big following. But there may be something to some of the rumors about her being irrational at times.
