That's not true.
Y'all act like men or males have some innate ability to locate another human being somewhere on planet earth by rubbing their temples, especially if they have money. It doesn't work like that.
One of my boys has M's. More than 10. Before ancestry.com and 23 and me popped off, this mf made it his mission to find out who his pops was, or what happened to him.
Long story short, he found him. He reconnected with him. He and his pops have been in contact for 8 years. Spent time together, talked, etc etc. That dude has another wife and family (that he lives with) and by ain't really trying to go back and change the past, make up for lost time. My boy is in his mid 30s, rich as fukk. There's nothing he can be taught at this point and there's no biological connect. His paternal grandparents are gone so there's some medical history that could be relevant but that entire wing of his family is just not there. He has some cousins and aunts, maybe an uncle out there but my boy ain't trying to meet with a bunch of strangers, even if it's blood and introduce them to his family and try to make things work. He just wanted to know who his pops was and what happened. His pops is happy for his success but that's about it. Never asked for anything, doesn't want anything and isn't entitled to anything.
For all we know the singer did the leg work to get closure for herself.
