Kendall and Kylie Cheer On Their School

Kendall and Kylie Jenner seem to have the best of both worlds. The Kardashians' younger half-sisters, 15 and 14, respectively, have found a way to live life like ordinary teens when they want, and with the glitz and glam of full-fledged Kardashians when they want, too. For proof, look no further than the photos snapped of the sisters cheering side-by-side in cheerleading uniforms for their private school, Sierra Canyon, in L.A. on Saturday.

The flashier side of the duo's life was recently revealed as Kendall and Kylie modeled prom and pageant dresses by Sherri Hill for a photo shoot. According to Women's Wear Daily, Kylie has even been selected to walk the runways at New York Fashion Week! On Monday, she's expected to strut her stuff for Abbey Dawn, a teen clothing line by Avril Lavigne, the rocker and girlfriend of her half-brother, Brody Jenner.

Of course, almost everything the youngest stars of "Keeping Up With the Kardashians" do these days causes controversy, and Kylie's planned appearance is no different. Diane von Furstenberg, the president of the Council of Fashion Designers of America, has been very vocal about requiring models who hit the runway to be 16. The designer is even encouraging others to I.D. their models on the day of the show to make sure they're of age. "The casting agents for the Diane von Furstenberg show will be doing this and we encourage others to do the same," she wrote in a letter to designers.

Oops, I guess Avril's got lost in the mail. Do you think there should be an exception for Kylie?
