Here's the deal:
According to Nicole and Lionel on the show:
He and Brenda were backstage at a Purple Rain show. There was this adorable girl wandering about. She wasn't really supervised, but she was JUST there. Her parents or one of them was in Prince's band/entourage at the time. We all know Sheila E was the opening act for that tour.
Brenda and Lionel became Nicole's foster parents, if you will. This was when Nicole was 4. It wasn't until 8 that they officially adopted her. Nicole didn't mention who her biological parents were.
Lionel mentioned that Diane soon to be ex-wife #2 only made a "wish list" if you will. She is asking for what was published, but she will not get it.
Nicole is 21 or 22. I forgot which one she said.
She explained that when Lionel and Brenda split it was BAD! She in fact had to become the "parent" because Brenda must have gone through a depression. She said that Brenda wouldn't get out of bed. Instead of dealing with the divorce of her parents, she had to become Brenda's parent. She said she knew that Lionel was having the affair, "everyone knew" according to Nicole. She wanted someone to be the better person and tell her what was going on. She said she would stay out until 6 AM drinking, partying and doing drugs. She had no structure growing up. Your father is gone, he's not only working, but no longer in her life. Your mother is depressed. Your real parents gave you away....what are you to do? She becamse estranged with her father b/c she felt that she had to take care of her mother, so Lionel "felt" he had to step back.
That's your commentary. If you want to know more, watch for Oprah's reruns.
