It looks like Pippa Middleton decided to finally discuss the famous dress that made her bum famous.

According to Us Weekly, while attending her sister's, the Duchess of Cambridge's wedding in April 2011, the Vanity Fair columnist who served as the Maid of Honor managed to grab attention by wearing a figure hugging Alexander McQueen dress.

While giving her first public speech on Tuesday, February 25th at an event in London, Kate Middleton's little sister addressed both the fame and infamy that was a result of wearing the ensemble.

The 30-year-old said, "As I have found out, recognition has its upside, its downside and - you may say - its backside."

One of the guests from the dinner which was held at the Savoy Hotel by the Women in Advertising and Communications London group told the Daily Mirror about the socialite's sense of humor.

The onlooker said, "It was unbelievable how open she was - I don't think anyone was expecting that," adding, "She came across as really grateful for the opportunities but also talked about the pitfalls of her position."

In the past Pippa Middleton was dropped by her American publisher, Viking Press, after selling just 18,000 copies of her entertaining book.

Pippa Middleton confessed to the audience that it was "difficult" to read the negative reviews following the release of the book.

However, on a happier note her love life is pretty great seeing as she been dating hot British stockbroker Nico Jackson since early last year.
