OK, he’s a bit wrinkly – but who wouldn’t want a Jagger Baby and a juicy pension?

WHAT do you think about Mick Jagger fathering another child at the age of 72?’ I asked my only daughter. She grimaced. ‘Gross,’ she said. My daughter is 22 – ie only seven years younger than the new baby mother, Melanie Hamrick. And unlike the couple, who declared themselves ‘surprised and happy’ by the stork’s visit, she knows exactly what happens when a great-grandaddy meets a beautiful ballerina less than half his age and they love each other very much.

But still, I had to explain why I don’t share her revulsion and I do get why Sir Mick has knocked up his loved-up girlfriend. You won’t hear any limp jokes about how Miss Hamrick could soon be changing two sets of nappies from me.

‘But he’s Mick Jagger, darling,’ I said, as if that explained everything. Then I went on. I can – just – remember what it feels like to be a nubile woman, wanting a baby with someone. Having experienced baby hunger myself at the same age as Miss Hamrick, I don’t think this is just about a rock god showing us there’s still plenty of lead in the pencil (or what Keith Richards cheekily called ‘his tiny todger’).

Nor is it a case of whatever Ronnie can do (Wood, aged 69, has just had twins with his girlfriend) Mick can do older, and better.

This isn’t about a bloke proving he’s still got it, darling, I continued (deciding not to make an ‘Arise, Sir Mick’ gag), who wants to show he can have a baby with his new squeeze whereas his ex can’t (Jerry Hall is 60, and her husband Rupert Murdoch is 85, but I wouldn’t put it past any of them on current form).

I think Miss Hamrick is genuinely into the leathery old ledge, and vice versa. After all, Sir Mick has a good rep as a dad (he has so far seven kids by four women) as well as a sugar daddy. It’s not a track record that would catapult a woman into the maternal hall of fame, but as we know, men and women are judged very differently when it comes to these things. Furthermore, he’s a

ALASTAIR Campbell has called for a second EU referendum and said my bro’s appointment to a great office of state ‘has gone down like a global dose of the Zika virus’. I trust Theresa and think that Boris will be a brilliant Foreign Secretary. And Alastair: you OK, hun? banker when it comes to the providing side of things. Indeed, as the late Mrs Merton would no doubt have asked of Miss Hamrick: ‘So what first attracted you to the global superstar worth £270million?’

The lucky lady won’t just be having any old baby with some wrinkly she hooked up with a couple of years ago. She’ll be having a Jagger Baby with a capital J.

Just as women queued up to have babies with an antique Lucian Freud (who had 14 acknowledged children and, it’s believed, 25 unacknowledged), the fact is that very famous, very rich men don’t grow old in quite the same way as the rest of their sex grow old in a woman’s eyes.

NEVER, ever, underestimate the power of the brand when it comes to the female’s procreative choices. Never, ever underestimate the power of financial security when it comes to our selection of a mate. Miss Hamrick is having a Jagger Baby and has sorted out her pension at the same time.

I’m sure the rest of the Jagger litter are feeling a little dusty about it (unnamed friends insist they are ‘taking it in their stride’). But Mel has killed at least two birds with one Stone (even if this one doesn’t have time on his side).

In fact, come to think about it – even though he looks like a spatout, half-chewed toffee – I’d be jolly thrilled to have a Jagger baby, too.
