Amid rumors that Kate Middleton is concerned about Pippa Middleton's future brother-in-law, a new report claimed that the Duchess of Cambridge will have to skip her sister's wedding. Life & Style magazine reported Saturday that Queen Elizabeth II has "banned" Kate and Prince William from attending the wedding.

According to the report, the reason behind the queen's decision is Spencer Matthews, who is the brother of Pippa's fiancé James Matthews. Spencer, who is a reality star and model, reportedly posed in public wearing nude underwear to promote a new style website during the London Fashion Week. Spencer's actions have raised concerns in the royal family, which is worried about any embarrassment, the report claimed.

Life & Style magazine also reported that Kate was heartbroken after she learnt about the queen's decision, adding that Pippa "still expects Kate to show at her wedding.”

However, Gossip Cop debunked the report saying that the queen will not stop Kate from attending her sister's wedding, which is expected to take place next year.

Last week, reports surfaced that Pippa is busy with her preparations and wants “Hello” singer Adele to sing at her wedding. Pippa’s wedding to James, who works as a hedge-fund manager, is speculated to be taking place next summer.

Most recently, reports surfaced that Pippa's iCloud account was hacked and about 3,000 photos, which also included some intimate photos with James, were being shopped. A probe has been launched into the case and one person has been arrested.

Last week, a judge in U.K. ordered a ban on the publication of photos stolen from the iCloud account.
