The latest whisper comes from Yvonne Yorke, royal correspondent for the Huffington Post, who claims she has known the identity of Middleton's wedding dress designer for four months, however kept it a "secret in accordance with palace wishes." Until now...

"A St. James's Palace spokesperson I talked to won't confirm or deny that Cranston had been selected, only saying, 'e are not being drawn on any speculation on the wedding and cannot comment,'" she reports.

"From what I've uncovered, the reason the palace did not announce the designer's name (as they did with the Emanuels who were confirmed just one month after Diana's engagement) was to protect Cranston and her family from media scrutiny for as long as possible, and to allow her the freedom to create the wedding gown of Catherine's dreams without additional pressures and distractions," she added.

Kate is no stranger to Cranston's work, she wore a black Libélula velvet dress coat with a diamante clasp to a friend's wedding in January (pictured). While the exact design of her wedding dress remains a secret, the Daily Mail has been told it is ivory satin and lace, with a pearl button detail and a 10ft train.

As I keep saying, only time will tell...
