Lyric discussion by chi-chi 

It's simple the man slept with Billy Jean. He tells his current girl he was never with the other chick, that the child is someone else's. In the end the mother of the child shows up tells his girlfriend what really happened and he can't depute because the baby looks like him. He played around regardless of what his mother had told him and he got caught up like she said he would.

My interpretation was that he was associated with Billie Jean, and then she claimed there was more to than there actually was

@chi-chi I could see that if it weren't for the line about his girl crying because the child's eye's were his. That denotes the child had his features. I take the "danced the floor..." lyrics as euphemism them fooling around. That's also why he's saying the line about advising ppl to thing twice about what they do. So while she wasn't actually a lover they messed around at least once
