Taylor is just one of Barbara's 10 Most Fascinating People of 2014 and ET has an exclusive sneak peek at the special.
2014 was no doubt the year of the booty. While singers like Nicki Minaj, Jennifer Lopez and Iggy Azalea flaunted their assets, Taylor Swift maintained her reputation of being the girl next door. Barbara Walters recently sat down with the "Shake It Off" singer for her annual Barbara Walters Presents: The 10 Most Fascinating People of 2014, and grilled Taylor on her good girl image.
"Well I do drink, I'm 25," she tells Barbara. "But I did wait until I was 21 because I was worried about getting into trouble."

In the TV special, which airs Sunday night on ABC, Taylor also opens up about the responsibility she feels to be a good role model to her young fans.
"I put everyone of my actions through a filter before I do them because that's the way my life is," she says. Speaking hypothetically she adds, "If that story gets out or some 10-year-old sees that I did that in a news article, like my actions do have ripples."
"She's squeaky clean, she likes this," Barbara told ET. "It certainly has added to her career - she's one of the biggest stars there is today."
Barbara also scored a rare sit-down interview with new mom Scarlett Johansson, who also made the list this year. It was Johansson's first TV interview since giving birth to daughter Rose Dauriac on Sept. 4.
"It's wonderful," Scarlett says of motherhood. "It's very magical and exhausting."

Scarlett, who secretly married Romain Dauriac one month after Rose's birth, also shared how she's shedding the post-baby weight.
"[Breastfeeding is] the best way to get back in shape," the 30 year old explained.
Barbara, a veteran journalist and former host of The View, has been doing her 10 Most Fascinating People interviews since 1993, and tells ET this may very well be the last one ever.
"I have been doing the 10 Most Fascinating People for 21 years. That's a lot of fascinating people," she admits. "This probably will be the last one I do. Although I said that last year and here I am again."
