No "what kind of tree would you be" softball questions here!

Barbara Walters didn't pull any punches interviewing the Kardashians on her eponymous 10 Most Fascinating People of 2011 special, which aired Wednesday on ABC.

In a sit-down with Kim, Kourtney and Khloe Kardashian and their mom Kris Jenner, the veteran journalist looked back on Kim's initial brush with fame: Her 2007 sex tape with Ray J that stormed the web and made her a household name.

"So, was it a good thing to have done?" Walters asked of the X-rated clip.

"Whatever you do, you might think," Kim, 31, replied, stammering. "I've made mistakes in my life for sure."

Added mom and manager Jenner, 56, of the brouhaha: "It was devastating for the whole family. You cry yourself to sleep for a few nights, then you hire an attorney."

Walters also brought up a frequent complaint about the family and other reality stars: "You don't really act; you don't sing; you don't dance,…You don't have any — forgive me — any talent!"

"I think it's more of a challenge for you to go on a reality show, and get people to fall in love with you for being you," Kim mused.

Added Khloe: "None of us think we have talent. none of us think we can sing or act or dance."
