Weird Stripper Love Triangle?

Okay, its really not that "out there" but I am in need of an objective opinion. This could get confusing but about a week and a half ago I was eating late night with 2 work friends at Denny's. Another table of 2 females and 2 males came in and were visibly intoxicated. I was facing one of the couples of which the male looked familiar. Every time I looked in their direction the male was staring at me and the girl was cutting me some nasty looks. I overheard her saying something to the effect of "awkward situation". She went outside and her friend followed her. When my friends and I walked outside to leave, she was sitting on the curb having a meltdown. Last Saturday I attended the pre grand opening party for employees of a new upscale club in my city I will be working at and the same group of people were there as well. Again, the male was staring and the girl was cutting me the dirty looks again. Now I am generally over paranoid about things like this but I almost always leave it alone but my friend noticed it too and she is NOT the paranoid type at all. I was racking my brain trying to figure out who these people were and why they would have a problem with me. The following day (sunday) I finally realized the male looked familiar from visiting a friend of mine from time to time at my previous club (which I was fired from when they found out I was leaving for a better club) but that didn't answer my question about why they would have a problem with me. The next day (yesterday) I called my friend whom he had visited to ask who he was and she told me about how they were friends and he was a great guy. When I asked about the "girlfriend" she expressed in some choice words her dislike for the girl and explained her psychotic episodes and the fact that they were not actually seeing each other, just "talking" and that she was obsessed with him. She also told me about the girl she was with that night who happened to be a dancer at the club I am currently working at until the new club opens in a couple weeks and the one I had mistaken for his "girlfriend" also worked there as a waitress. She didn't know any reason they would be angry with me but I at least knew who they were and thats all I really wanted to know. My friend (to my surprise) called me back 30 minutes later saying she called him (they're pretty good friends) and told him what I called her about and to question why he was still hanging out with her. He knew exactly who I was from the party and told her he thought I was gorgeous. He also told her that he couldn't take the crazy any more and he was going to let her know that they shouldn't be hanging out because she was misinterpreting the situation and acting like a jealous gf, and he did exactly that. My friend suggested we all meet up so I could see that he was a really great guy and gave him my number. We've been talking since then and seem to get along famously (so far, right? haha) and I admit, I am a bit taken with him (can't lie, he is gorgeous and a very nice guy with references) and I am shocked by the chain of events also. He told his friend that he and I were talking and he was attracted to me. Tonight at work things were very strange and I have reason to believe his friend leaked some info. Now here's my concern, I have not spoken to either one of these girls in the very short time I've worked there but I do know they can't be described as "stable" or "level headed". I intend to mind my own business but I am unsure how to handle the situation should a confrontation happen. Also, I am attracted to him and he does seem genuine. I would like to see where things could possibly go. I don't feel like there was any wrong doing to this girl by either of us considering they were not a couple and I had no intention of talking to him when I called for info. Also, keep in mind both of these girls will likely be working with me at the new club, I ume after seeing them at the employee party. I need some advice on how to handle these 2 hostile girls if I am approached, short term and long. Sorry this was so long winded but I wanted to include as much detail as possible since it was such a confusing chain of events. Thanks in advance for any insight!
