Pippa Middleton has solidified her position in the world as a truly fascinating person.

The younger Middleton has landed herself on Barbara Walters' coveted 10 Most Fascinating People of 2011 list.

All eyes have been on Pippa since she walked down the aisle in sister Kate's wedding in April of 2011. Wearing a stunning Alexander McQueen, curve-hugging gown she made jaws drop around the world as people asked, Who is that girl?

Now Pippa Middleton is a household name and one of the most sought after bachelorettes in the world. From her fashion sense to her party planning, from her break ups to her $500,000 book deal, no one can stop talking about Pippa.

It is no wonder that Walters chose to put the brunette beauty on her list. How could she not?

Another young starlet who made the list is none other than Katy Perry. The pink-haired pop star has had quite a year, standing out as one of the hottest names in the biz, and she is only 27-years-old!

Katy Perry has been on fire lately.

At the American Music Awards she was honored by Heidi Klum with a special achievement award for her amazing success in 2011.

In August, she was proclaimed the first female artist to ever have five #1 singles from one album on the Billboard Hot 100 chart for two consecutive weeks. At the 2011 MTV Video Music Awards she got 10 nominations -- the most of the ceremony and the only singer in history to have four different music videos in multiple categories.

She just released her video for The One that Got Away off her Teenage Dream album.

Middleton and Perry join Walters' list with other big names including: the Kardashians, Simon Cowell, Derek Jeter, Donald Trump and Jesse Tyler Ferguson and Eric Stonestreet from Modern Family.

Each year Walters chooses the individuals who have had the most clout (and the most headlines) that year.  But who will earn the title of Most Fascinating of the year? You will have to wait, and watch, to find out.

The show, Barbara Walters Presents: The 10 Most Fascinating People of the Year, airs Wednesday, Dec. 14 at 9:30 p.m. EST.
