Kendall Jenner Towers Over Sister Kourtney Kardashian in Instagram Pic
Looks like Kendall Jenner is the big sis now -- height-wise, that is!
The 19-year-old towered over her oldest sibling, Kourtney Kardashian, in this fun Instagram pic posted by sister Kim Kardashian.
Kim captioned the post, "Twins," and with their matching white button-down shirts and long dark locks, Kendall and Kourtney really do look alike!

Kendall put on black heels while mom-of-three Kourtney, 36, went barefoot to exasperate their height difference. Without footwear, the Calvin Klein model is just shy of 5'11", while the eldest Kardashian kid tops out at 5 feet.
Even mom Kris Jenner got in on the joke, regramming Kim's photo with the caption, "Not sure how this happened but I gave birth to both of them ... #legs #love #familyfun #beautycomesindifferentshapesandsizes #blessed."
After the shoot, Kendall showed off her hair skills in a "3 snaps we out pony" move.
It's nice to see the girls joke about their beauty differences, though they've always been open about their looks -- both what they love about themselves and their insecurities.

Even though Kendall is doing very well in her modeling career (just look at those long legs!), she admitted to Allure that after battling acne in high school, she's still working on her self-esteem.
"I still have a hard time looking at someone when I'm talking to them, and I get nervous," Kendall told the magazine. "When I started getting in front of the camera a lot, I think my confidence started to come out. It took a minute, because I had to believe in myself."
The youngest of the Kardashian krew, 17-year-old beauty chameleon Kylie Jenner, also deals with insecurities. She recently revealed that she gets temporary lip fillers, frequently changes her hair color and just tried out lighter contacts for a new look.
