Kylie Jenner Admits She's Inspired by Kanye West: He "Makes Me Want to Work Harder"

Exclusive: Sisters gushed about their future brother-in-law

Kendall and Kylie Jenner made their foray into the world of accessories with the launch of their handbag and shoe collection for Madden Girl.

The sisters stopped by Nordstrom at the Americana at Brand in Glendale, Calif. over the weekend and sat down with E! News to dish about their latest project.

The Jenner girls gushed that Kim Kardashian's fiancée, Kanye West, gave them inspiration to focus wholeheartedly on their designs.

"He's really inspiring, just watching him. He's been my roommate for a couple months now; he's so passionate about his stuff and he's always showing me his designs," Kylie explained.

"He's such a creative guy, he's awesome, he has a lot of talent. So it's cool to see that. It's inspiring and it makes me want to work harder and be more into it, so it's cool."

To celebrate the launch of their new line, Kendall looked stunning in a high-waist black skirt and lacy black top while her sis stood by her side in a navy strapless jumper.
