LONDON (DM) - They are reported to have separated after a two-and-a-half year relationship. And, while neither Donna Air nor James Middleton has openly commented on the alleged break-up, the 36-year-old blonde has shared a cryptic post on her Instagram page in the wake of the news. The model and TV presenter is said to be ‘more than a little heartbroken’ over the split from the Duchess of Cambridge’s brother, and has been lying low in the wake of the separation. But on Wednesday evening, as the news of the shock split came to light, she shared a poignant message on her social media page. The former Big Breakfast host posted a snap of an inspirational quote written on a chalk board at her bikram yoga class, appearing to confirm the rumours of a break-up.

It read: ‘Accept what is, let go of what was, have faith in what will be (even those itchy ears).’ Her supposedly meaningful image came as it was reported in the national press that Donna’s long-term union with James had sadly come to an end.

A source told The Sun: ‘The split happened a couple of weeks ago and it was James’ decision. ‘He just didn’t think it was going to go the distance. And I think his family were always very anti her being the future Queen of England’s sister-in-law.’

The news comes as something of a surprise since Donna and James were pictured putting on a very loving display in St. Barts just last month.

The alleged split sadly comes just a few days after Donna’s beloved grandmother passed away, for whom she has helped raise over £1.5k in honour of Alzheimer’s Society.
