People seem to think the big deal in 
this story is that Madonna is about the same age as her new beau's grandma.
But hold on just a moment...the "kid" is 22.  Madonna is 51.  His grandma is 51?  Oh, and his mom is "14 years younger than Madonna" and is pissed.
Let's see, 51-14=37.  37-22=15.
So, lady, you had your boy at age 15.  And grandma had you at around that same age.  At least your son's an adult!
