Beautiful People 2010: Kendall & Kylie Jenner

If you kept up with Keeping Up With the Kardashians last season, you saw that as Kourtney, Kim and Khloe started their own families and dramas--not always in that order--the two youngest members of the klan, Kendall and Kylie Jenner, 14 and 12, emerged as budding personalities in their own right. When Kourtney hopped in the shower after her water broke, it was Kylie that delivered the season's best line: "Let's get clean so we can get blood all over my vagina!"

"People tell us all the time we should have our own show," says Kendall, who's modeled for Nordstrom and Forever 21. "I absolutely love it--everything about it!" she says of modeling--especially bonding with her sisters. "Kim gives me advice and Khloe tells me how lucky I am because she always wanted to be a model," offers Kendall. "She gives me pointers--it's like I'm Khloe in another body."

"It may not always look like it on the show, but our sisters are just really good role models," adds Kylie, who's eyeing acting. As the family grows, so do the role models. "Lamar [Odom, Khloe's husband] told me the most important thing in a relationship is to be able to trust the guy," remembers Kendall. Not that she's had to use the advice yet: "We don't date," she says. In fact, for growing up in a family where mom's Christmas parties meant visits from Sugar Ray Leonard and Babyface, the girls are still pretty much normal tweens, doing charity work at school, shopping at Planet Blue in Malibu and hitting the beach--when Kylie doesn't have a bar or bat mitzvah to go to. Sure, they have their celebrity crushes--but for the right reasons: "We're obsessed with Britney Spears," says Kylie. "I've been listening to her songs since the second grade." But mostly, adds Kendall, "We like her because she's someone who's really turned her life around." Hear that, Scott?
