Khloé Kardashian Odom's living the life—but the road to happiness and self-confidence hasn't been without its bumps.
"I was called fat all the time," she recalls in an interview with E! News' David Burtka airing today. "I've always been compared to my sisters, who are beautiful and who have always been."
Kardashian, who has spoken out against bullying and worked with the "It Gets Better" campaign, says that at 5 feet 10 at age 13 and with lighter skin than her sisters, she always stuck out.
"I feel like I was so attacked," Kardashian. "[I was picked on because] I had to wear braces, I was overweight as a kid, just for no reason."
Even to this day, adds the E! star and household name, she still gets treated like the ugly duckling.
"I'm called the fat sister...I'm called the ugliest Kardashian," she says. But the haters don't hurt her the way they used to.
"I'm proud of myself," Kardashian declares. "I could break and go get all this plastic surgery and get my nose fixed and get lipo or do whatever, but I haven't chosen to do that because I know I'm a great person. I'm pretty damn hot, if you ask me."
Regarding the still-rampant issue of bullying, Kardashian says that she would love it if kids could focus on "how many positives they have."
"Typically people get bullied because [the bullies are] afraid of that person," she observes. "There's a spark, a light, something that the bully doesn't have—and they're intimidated, so they want to attack you."
As for her fellow adults who may be witnesses to child-vs.-child bullying and who decline to step in, saying they don't want to interfere, Kardashian has no patience for such things.
"A lot of adults don't think it's their place to interfere with kids," she says. "I interfere all the time."
