These are Michael Jackson's three children, Prince Michael I, Paris Michael Kathrine and Prince Michael II (the late King of Pop was not very creative with names).
And this is Deborah Rowe, the handsome(?) mother of Michael Jackson's two children.
Deborah is Jewish, which makes PM I and PMK (but not PM II, whose mother was supposedly an egg donor) half-Jewish.
There are many, many jokes we can make here, but we're going to respect Jackson's legacy.
