Kendall Jenner is clearly a master at keeping her dating life under wraps.
ET caught up with the 19-year-old supermodel exclusively at New York Fashion Week on Friday -- where she was promoting her first fragrance campaign for Estee Lauder's Modern Muse Le Rouge, since becoming the face of the company
last November -- when she dished on why she's never been publicly out with a significant other. Last month, she was linked to Nick Jonas
after reportedly being set up by her bestie, Gigi Hadid, and her boyfriend, Joe Jonas, though the "Jealous" singer quickly shut the rumors down
"It's not always easy, but I don't know, I just like to keep my private life private," Kendall told ET about keeping her dating life on the down low. "I try my best, but at the same time, I try not to let being out with someone affect my everyday life. Like, if I want to go out and grab a smoothie with a friend who's a male, I'm not gonna let the paparazzi stop me from doing that and living my life and just being a normal person."
"I try to keep things as private as I can, but when it comes to a point, it's just not a big deal," she added.
During the candid chat, Kendall also revealed the surprising way her big sister, Kim Kardashian, told her she was pregnant with baby number two!
"I was at Coachella when Kim told me and she FaceTimed me, and I was in, like, a supermarket, and I was like, 'Shhh be quiet, there's people around!'" Kendall recalled, clearly protective of the 34-year-old reality superstar. "'I know you're trying to keep this on the down low right now and I'm in the supermarket!'"
In a new promo for Keeping Up With the Kardashians
, it's revealed that Kim actually told her and Kanye West's adorable 2-year-old daughter, North West, the big news first, but Kendall shared she couldn't care less about which one of the sisters she told next.
"It's not that big a deal between us -- we all know we're equally special and important to each other," she stressed.
"She's just beautiful, it's ridiculous," she gushed. "She always steals the show."
"I don't know," Kendall said about whether or not North has modeling in her future. "I think that she's definitely gonna have a life of, just like, awesomeness. She's definitely gonna do some stuff like that. I can't see it any other way, that face is just too good."
"She's awesome," Kendall said of the Tron: Legacy star. "I just assume no one knows me."
ET actually caught up with Kendall's younger sister, Kylie, on Tuesday at the Vera Wang fashion show, where the 18-year-old star addressed the criticism over the monthly subscription fees for the Kardashian/Jenner clan's brand-new mobile apps
