Kendall Jenner has been frequently criticized for being 'too skinny'.

Unlike her Kardashian half-sisters, Kim; Kourtney; and Khloe, Kendall Jenner lacks a curvaceous figure, as she inherited her father's athletic body.

Kendall Jenner is the daughter of Olympic decathlete and gold medal-winner Bruce Jenner and mother Kris Jenner.

According to Daily Mail, Kendall Jenner, a young model and reality TV star, appeared in Harper's Bazaar Arabia and said, "I'm constantly criticized for being too skinny. I'm trying to gain weight but my body won't let it happen."

"What people don't understand is that calling someone too skinny is the same as calling someone too fat," Jenner said.

Khloe Kardashian Odom recognizes Kendall Jenner's plight; she called her half-sister a "supermodel who eats crap all day."

Kendall Jenner began appearing on Keeping Up With the Kardashians in 2007, and started modeling at age 14.

Jenner signed with Wilelmina in 2010, and has been trying to carve out a different career path from her famous half-sisters.

She said, "I'm trying my best with what I want to do, which is modeling. I think I'm on my own career path and I don't really care what other people have to say about me being in the spotlight of my sisters. I'm just doing my own thing," she told the magazine.

Still, it seems that Jenner's half-sisters will support her, whether she wants to be associated with the family reality show or not. "Kendall's Harper's Bazaar Arabia spread is so stunning! She did an amazing job and the photos turned out absolutely gorgeous. Xo," Kim Kardashian posted on her blog.

Khloe Kardashian wrote, "How gorgeous does Kendall look in her Harper's Bazaar Arabia spread?!? I cannot get over these pics! She is absolutely breathtaking."
