From posing for sexy modeling pictures to taking birth control pills, 15-year-old Kendall Jenner is becoming the hardest Kardashian sibling to keep up with these days.
Case in point: Kim, Kourtney and Khloe Kardashian's kid sister hit the Teen Choice Awards in Universal City, Calif. earlier this week rocking a cleavage-baring Aurelio Costarella minidress with dramatic smoky eye shadow. It was a major change from the age-appropriate minimal makeup and blue tank dress (which matched her 13-year-old sister Kylie's ensemble) she wore to the Prom premiere back in April.
The leggy brunette has even caught the eye of Justin Bieber. The 17-year-old singer is trying to set Jenner up with his writer/producer pal, Julian Swirsky. Early Tuesday morning, Bieber tweeted: "Hey Kendall Jenner, you should let my boy [Julian Swirsky] take you out on a date."

So will she let Bieber's bud take her out? "Only if you and Selena Gomez join," Jenner tweeted back Tuesday. "Double date!"
Swirsky, who is 16 according to his Twitter bio, responded to the Never Say Never star's suggestion about taking Jenner out on a date: "Yeah, I wouldn't mind that."
