Reading that article, you would never known she had ever been married. She makes it sound like she found the house with the help of her mum and moved in there alone. She talks about redecorating the front room, which happened soon after they announced their split, if I recall, and she's made it into a much more feminine space. This seems like the obvious space to mention her marriage split - but it seems like she doesn't want to mention it at all and has possibly also asked the journalist to omit any mention. Maybe this is her way of dealing with the split, but it does feel like Joe has been somewhat erased from her life, and makes me think that there's more to their split than simply 'growing apart.'
The above is not meant to be critical of her - it's just an observation. I know she likes to keep things private.
