Believe it or not, Kim Kardashian wasn't always the super-glam center of attention in her family. Now an outspoken 29 year-old, young Kim could be shy -- even a bit of a plain Jane! -- childhood pals tell Us.
"I don't think she wore any makeup other than mascara," her friend Meg Hall says in the new issue of Us Weekly.
So how did Kim do with the boys? Not as well as class clown Khloe. "Everyone thought Khloe was cuter," a friend tells Us of the younger sister, now 25 and married to Lamar Odom. "She looked all American, so she got more attention."
Meanwhile, back in the day, Kourtney, now 30 with baby boy Mason, had a family rep for being a goody-goody, and bragging about her stellar grades to Kim and Khloe.
The three eldest sisters apparently always bickered as they do today on Keeping Up with the Kardashians.
"In high school, Kimberly stole some of Kourtney's jeans from her closet," stepdad Bruce Jenner tells Us. "Kourtney walked into her classroom, and in front of everyone she said 'Kimberly has my jeans. I want them back!'"
But the threesome also bonded over the fashion indignities their mother Kris Jenner subjected them to. "I loved to dress all three alike and put huge bows in their hair," Jenner, 54, tells Us. "They still haven't forgiven me!"
