Kendall and Kylie Jenner shy away from the cameras as they pick up a few treats at their local Ralph’s grocery on Monday afternoon in Calabasas, Calif.

The youngest siblings of the Kardashian-Jenner clan cover the March 2012 issue of Teen Vogue mag!

“so excited to show you guys this cover! Had so much fun and it’s such an honor to be on the COVER of Teen Vogue!!!” Kendall tweeted yesterday afternoon.

Big sis Khloe shared with the mag about playing their second mom: “I don’t let them look at blogs. They are toxic. Kendall and Kylie are like my babies.”

She adds, “I literally raised them, and I make sure I’m still very involved in their lives. I have access to all of their social media outlets. They are not allowed to have Twitter or Facebook unless I have the password. I’m very protective, but in doing that they also feel like they can talk to me about anything, and they do.”

Kendall and Kylie Jenner smush themselves together to capture a pic in this new shot from the March 2012 issue of Teen Vogue.

The two cover girls, BFFs, and sisters opened up to the glossy about cheering, style and family. Check it:

Kendall on cheerleading: “They call me Cheer Mom, because when we make those big banners for football games, I’m the one to say, ‘Do this, do that; use this color, use that color.’ Not, like, in a mean way. But I just like things in order. I’m a perfectionist.”

Kylie on her shopping habit: “I feel like a shopaholic. When I come home with a new bag of stuff, oh my god, it feels so good.”

Kendall on her own style: “I like to be comfortable and casual. I’m more laid-back than Kylie. In school, I’ll wear jeans, a sweatshirt, and Uggs, and she’ll [Kylie] wear, like, this whole ensemble that she put together the night before.”
