If you ask Barbara Walters, Kim Kardashian and Pippa Middleton are two of the most fascinating people of the year.

ABC announced the TV personality's coveted list of 2011's most talked-about stars Wednesday, with the reality star and Kate Middleton's little sis making this year's cut.

Also highlighted in a December 14 ABC special will be Kardashian's sisters, Kourtney and Khloe, X Factor's Simon Cowell, Derek Jeter, Donald Trump, Katy Perry and Modern Family stars Eric Stonestreet and Jesse Tyler Ferguson.

Speaking to Us Weekly's Alexandra Houck, Walters said that while her most distinguished person has yet to be revealed, Cowell sure impressed during their sit-down chat.

"He was very outspoken and funny and charming," Walters said of Cowell, whom she interviewed on a Saturday before flying back home on a redeye flight the next day. "I watch him on the air and he can be so wicked and mean. I loved him! I loved being with him. If it hadn't been a good interview I would have killed him!" she joked.
