We all know what a MILF is.

But my friend Vanessa, whose daughter is pregnant, tells me she wants to be a GILF. In the papers this weekend, we learned that Mick Jagger’s daughter Jade is, like Vanessa, expecting her first grandchild. And that raises a rather grisly question: Does Sir Michael now have ambitions to be the world’s first GGILF? Oh God, he does, doesn’t he?
