This kind of garbage is another example of why the Supremes story is holding less and less interest and why they are unable to attract anything like a Lifetime Achievement Award from the Grammys or anyone else ~ it is a spectacle and it is not an attractive one.
There are so many people out there trying to "hawk" a connection to Diana Ross and turn it into money.
