"She's definitely gorgeous – she looks better than most 20-year-olds in their bikinis!" Khloe, 26, told UsMagazine.com Saturday at the SWAGG Mobile Application Lounge at the Mercedes-Benz Polo Challenge at Blue Star Jets Field in Bridgehampton, N.Y.
"Also, in the modeling world, being 14 is actually 'middle age,'" Khloe went on. "Kimora Lee Simmons was walking for Chanel in Paris at age 12; no one commented when she did that. So if you want to speak in modeling perspective, you have to live in a modeling world. Not that many people are putting it in that perspective. They're just thinking, 'Oh, Kendall Jenner. Let’s talk some crap.'"
Khloe told Us her sib "has a great head on her shoulders. She's not buying into any of this hype. She’s doing what she loves to do. And it's a fun hobby for her."
She denied that her sister is growing up too fast.
"She's still a kid," Khloe told Us. "She is at camp, doing what kids do. She's doing a great job."
