Pippa Middleton became one of the most talked-about personalities after she was seen during Prince William and Kate Middleton's wedding in 2011. And she made headlines again when she announced she is marrying her boyfriend, British former racing driver, James Matthews. Following this, people are excited to know if the English socialite is going to have her sister as a maid of honor, like she did during Kate's royal wedding.

But rumors have been circulating that the Duchess of Cambridge is probably going to skip one of the most important event of her sister's life, and the reasons are unclear yet. But some are claiming that Queen Elizabeth II has told Catherine not to attend the wedding.

According to IBT, the whole royal family is reportedly forbidden to attend the wedding in accordance to the Queen's order. The source further implied that the reason for this is Spencer Matthews, James Matthews' brother and Pippa Middleton's future brother-in-law. Spencer, who is reportedly a model and a reality star, have publicly promoted a nude underwear during the London Fashion Week, and this has apparently worried the Queen and the royal family.

Meanwhile, in a report from Celebrity Dirty Laundry, one of the alleged reason of the Queen's refusal to go is Pippa's public image. Before Kate was married to Prince William, the sisters were reportedly often seen together with other socialites spending their time on parties and nightclubs. While the Duchess had toned down her 'party girl behavior' since marrying Prince William, Pippa has still been reportedly seen still doing such, together with the Matthews brothers.

However, a report from Life & Style magazine said that Pippa still expects Kate to show at her wedding. She added that she is in preparations for her wedding in 2017, and mentioned she wants "Hello" singer, Adele, to be present at her wedding.
