Take that, Kendall Jenner!

Lindsay Lohan's little sister, Ali Lohan, 16, is posing in provocative pics for her troubled actress/designer sibling's 6126 clothing line.

The teenage Lohan, an aspiring recording artist whose own attempts at fame were chronicled on E!'s short-lived "Living Lohan" reality show, is featured in two poses on the 6126 brand website.

The pictures have the same sexy-enough vibe that 14-year-old Kardashian half-sister Jenner projected during her recent controversial bikini shoot.

In one pic, young Lohan wears a barely there coral nightgown dress, and in another, a black lace minidress with a slim white slip underneath.

The pretty teen's brown hair is styled in retro waves, while her makeup is glam yet modest. And of course there's not a hint of a Scram alcohol-monitoring bracelet.

This isn't Ali's first modeling gig -- she was signed as a Ford model at age 3 and has appeared in Teen Vogue as well as ads for Rave.

A spokesman for 6126 tells StyleList that Ali's modeling was a reflection of her big sister's aspirations for the brand to have mass appeal:

"Lindsay and Ali are very close and it's very natural that they would work together. Lindsay is very excited about its Spring 2011 ready-to-wear line and feels it's a reflection of her style. These are clothes she hopes her teenage sister would wear. Lindsay wears them, but so does her mom, Dina. The idea is that 6126 is for everyone."

Although StyleList wouldn't exactly recommend that gray fringed number for biology class.
