In the upcoming episode of Keeping Up With The Kardashians, a heavily pregnant Kim Kardashian is concerned she has "lost her cool" and becomes obsessed with Kylie Jenner's style.

In the preview teaser, Kardashian thinks she's no longer stylish so she tries to figure out how to get Jenner to publish her photos on her Tumblr blog. She is trying to get approval from Jenner's teen followers through her official page.

Kim asks Khloe Kardashian how she can get on Kylie's Tumblr blog. An annoyed Khloe reveals Kim has been "Tumbr stalking" Kylie's blog.  Later, a frustrated Jenner reveals Kim keeps submitting pictures of herself for her to share with her teen followers on Tumblr.

In another teaser, Kim and Khloe are in a design meeting with Kourtney Kardashian and the staff that works on their Kardashian Klothing Kollection. When the sisters are presented with new fashion ideas, Kim tells the head designer she approves of it because she thinks Kylie would like it. She also said their youngest sister's personal style could serve as inspiration for their upcoming designs.

"Kylie my little sister, I think she would wear that," Kim announces in the design meeting, "She would wear something like that. That's really cool that it's shorter in the front that shows off her belly button," she explains.

She brought Kylie's name up again when she suggested they review the teen's Tumblr blog for inspiration.

"I'm not trying to be annoying but if you look at Kylie's blog she has all these cute quotes and sayings. It's so her soul and it's what I want our line to be," she adds.

Khloe questions Kim's obsession with Kylie. She said she believes because Kim is pregnant, she might feel like she is no longer stylish. Kim is seen reviewing Kylie's Tumblr blog and saying she wants to be "cool like that again" in the clip.

Episode 12 of Keeping Up With The Kardashians season 8 will premiere on Sunday, AUg, 18 at 9 p.m. EST/8 Central on E!
