So, shock horror, it looks like Coleen Rooney is snapping back into shape already after giving birth just a few weeks ago.
On her first night out with Wayne since their son Kai was born, she wore 6in Louboutin heels and a skimpy black dress.
It's a different world, isn't it? I didn't manage to go out with my husband until our daughter was over six months old, and skimpy black dresses were not on the agenda.
But wait - all is not lost. Some of Coleen's secrets have been revealed. So how do you get back into shape so quickly?
Well, it seems the first step is to be rich enough to hire a personal trainer. Coleen has been working out with Sheffield-based Elise Lindsay, who had her exercising until a few weeks before the birth.
According to the Times, since Coleen left hospital she has been following her trainer's "baby-nap express workout".
This means short sharp 25-minute bursts of exercise, which you apparently do while your baby is asleep.
This is assuming your newborn actually sleeps. In a cot. For at least half an hour. Which doesn't always happen. And I would recommend that if it does, you get some kip too. But that's just me.
Anyway, exercises include using a Flexi-Bar, says the Times, an instrument of torture shaped like a cane which vibrates when you lunge and squat.
The Times suggests performing lunges, stair-climbing, cycling and running to slim down your thighs.
Then there's the plié squat with side-step. The Times says: "Stand with your feet wider than hips and feet turned out slightly. Place your hands on your thighs and bend your knees to lower your torso towards the floor without leaning forwards.
"Keep the weight in your heels and think of the chest lifting as you bend the knees, while keeping a flat back. Then shift your weight on to one leg, dragging the other leg towards it along the floor using the muscles of your inner thigh.
"Separate the legs and perform the move on the other side. Repeat 15 times on each side. Perform 3-4 times a week as part of an overall toning routine and you can expect results within two months."
And if you can follow that, you're not as sleep-deprived as you ought to be.
What are your tips for exercising after the birth? Or is sleep more of a priority?
