Prince William and Kate Middleton’s marriage is once again in question after marital rumors spread involving the royal couple’s friend Rose Hanbury. The circulating news indeed affected the Duke and Duchess of Cambridge, who sought legal advice because of their concern over the alleged mistress.

Last March, the British royal family was rocked yet again with illicit affair news, this time involving the younger generation of royalties, Prince William and Catherine, Duchess of Cambridge. The tabloid headlines announced that the royal couple is on divorce talks, and the reason behind it was Prince William’s involvement with Kate’s longtime friend Rose Hanbury.

The rumors claimed that Prince William referred to Hanbury as “the one who got away.” Tabloids labeled Kate as a jealous wife, and the affair resulted in a rift between Kate and Hanbury. Prince William allegedly picked his side, and the royal couple considered a $250 million settlement.

Several credible sources shut down the news, but the rumors continue to persist. Kensington Palace has not given any official comment yet regarding the marital issues of the Cambridges.

While the royal watchers wait for confirmation from the Palace, an insider confirms that Prince William and Kate sought legal advice. The legal advice, however, involves the royal couple’s growing concern about how the rumor will affect them and the persons involved in Hanbury's life.

Hanbury was a modern and parliamentary researcher before she got married. Prince William and Kate share concern for Hanbury as a married woman and mother. The royal couple could not deny the fact the false rumors may hurt Hanbury’s family and her reputation.

The Marchioness of Cholmondeley is married to David Rocksavage, the Marquess of Cholmondeley. Hanbury and Rocksavage have twin boys, Alexander, Earl of Rocksavage, and Oliver, Lord Cholmondeley, and a daughter, Lady Iris.

Kate and Hanbury, once close friends, had a falling out, which was the purported basis of all the rumors surrounding the royal couple. The two used to be close friends, but Kate was accused of wanting to exclude Hanbury from her circle of network, at least according to the media. The Palace, however, denied the falling out rumors and called the false news as “inaccurate.”
