The couple, who have mostly been under the radar (they were collectively last 'seen' on these pages back in January, when Jamie was seen struggling through an Scottish airport with presumably his wife's bags) are reportedly splitting after 4 years of marriage. 

According to The Huffington Post, the "cracks began to show two years into their marriage", and the couple have been confiding in their friends (one of which has a right gob on them) that there is little chance of reconciliation. 

The Sun, meanwhile, have this from a source: "They are properly over as a married couple. It's gone past the point of no return. Jamie's just waiting for Kate to move forward with divorce proceedings. Neither are in any hurry but they both suspect there won't be a reconciliation. They accept they'll probably have to make some sort of statement but don't want to feel forced into anything."

As for the rumours regarding what started the cracks in the first place, seemingly Kate was jealous of Jamie's "friendships with other women", with The Sun's source adding: "Jamie's been clear that they've not been close for a long time. She's always been beyond jealous about his female friends and he was sick of it. Everyone's rallying around Jamie over it all and feeling very sad for him. Hardly anyone seems that concerned that Kate's going through a break-up too. She's burned a lot of bridges over the past few months."

While the couple haven't been seem together in months, Kate was last seen in the news when she got herself arrested at Luton airport after Sadie Frost's 50th.
