And little sister Kylie Jenner is clearly looking up to her curvaceous sis for posing tips.

Kim's half-sister posed with her bottom straight at the camera as she did a trademark Kimmy K backstage at New York Fashion Week yesterday.

The 15-year-old looked quite the superstar as she glanced wistfully into the distance with her hands placed around her waist.

Kylie, who was dressed in a slinky low-backed red ballgown, had just hit he catwalk with her sister Kendall for the Red Dress Fashion Show, to raise awareness about heart disease.

And she made sure she did the same pose as she and her sis were papped after the show in the official photos.

The pair showed off their incredibly slim figures as they strutted their stuff up and down the runway for the good cause.

While there was no sign of Kim Kardashian herself at the event, mum Kris Jenner completed the family affair by also wearing a Badgley Mischka gown and taking to the catwalk herself.

British star Kelly Osbourne also hit the catwalk - in a slinky sweetheart-necked fishtail red gown which clashed with her purple hair.

Kelly O looked like she was loving her model moment as she worked the camera and put on her best sexy face pose.

Meanwhile Kim Kardashian showed off her TINY baby bump in a black suit and monochrome striped jacket as she hit a social media conference yesterday.

When asked if she'd keep her child away from social networking sites, she said: “I would say yes, growing up in social media would be tough.

"I’m definitely going to be more protective with my own child, but I have more faith seeing how my little sisters have handled social media."

Kim even admitted that she has previously used Twitter to stalk her boyfriends if she didn't trust them and wanted to know where they were.

She added: "When I was in crazy relationships, if I had Twitter, that would have been the best stalking device ever."
