I think the problem is he's congratulating her for all her hard work getting fit when they are millionaires with access to a chef, nanny, cleaner, gardener, stylists, personal assistants, etc. Plus she literally lives with a personal trainer!
None of that means she didn't work hard, and well done to her she looks fab. It's just a lot harder to train and shift the baby weight when you've been up all night with your colicky baby before an 8 shift at Sainsburys then home to cook, clean, wash, walk dog, garden, admin, etc.
