She's modeled in ad campaigns for Forever 21 and designer Marc Clark, but Kendall Jenner may not have hit the catwalk willingly.
As a new clip from Sunday's episode of Keeping Up With the Kardashians shows, the 15-year-old Jenner says her big sis, Kim Kardashian, pushed her onto the runway.
When Jenner goofs off at a runway walking lesson and embarrasses her sister, she admits she never really wanted to do runway modeling in the first place.
"You knew from the beginning I've been scared to do runway. I really don't want to be here!" Jenner whines in front of the teacher, before storming out of the room, leaving Kardashian, 30, to cover for her.
Behind closed doors, Jenner — who made headlines last summer for modeling a sexy string bikini — slams Kardashian for taking out her frustration over a failed modeling career on her. "I feel like you're doing this for yourself," Jenner snaps.
"Kim originally wanted to do runway but she was too short for it, so I think she's taking her fantasy out on me," Jenner reveals when Kardashian is out of earshot.
Watch more of the sisters' emotional confrontation in the clip above, and catch the full episode of Keeping Up With the Kardashians Sunday at 10 p.m. (EST) on E!
