I read somewhere that our Mandy is a grandmother already but I have my doubts as to the veracity of the source.
I don't know enough to say definitively that this is true or false, only that Mandy does have kids old enough to have had kids (both pictured here:

So it could be she had found out back in 2015 when "Home Wrecker" was first released, and the oldest with the tag "GILF," that one of her kids was having a kid, and slipped that in as a nod to the fact she was a grandmother. She had kept secret that she was a mother all along, so why not grandmother too, as it wasn't really anyone's business to know.
And while we're out here speculating on bits and pieces, I'm now wondering if maybe this had something to do with her retirement, to help care for her granddaughter? And then possibly the speculated divorce she had, if there was disagreement over how much they may have been helping with the granddaughter, after raising her kids?
Again, just so we're clear, the only things I know for sure is that Mandy has a son and daughter who are old enough to have had a kid. Everything else is just me piecing things together, and may not be true at all. And there's nothing Mandy had told me years ago that would provide a better picture.
Enough of that, pretty pictures:
