Kylie 'thinks she has better butt' than Kendall

Reality TV star Kylie Jenner seems to be in a competition with her sister Kendall in terms of looks.

The youngest daughter of the Jenner-Kardashian family feels that she has a "better derriere" than that of her model sister Kendall.

"Kendall has always been the beautiful one with the model looks. But now people are really showing Kylie the love for blossoming into this beautiful young woman," a source told Hollywood Life, reports aceshowbiz.com.

"She's (Kylie is) curvy and voluptuous and she loves it. You can tell by her Instagram pics how much Kylie loves her body (sic)," the insider added.

The 17-year-old reality TV star aspires to have a derriere like Kim and Khloe Kardashian. Though Kendall has the model looks, Kylie prefers Kim's curvy figure.

"She thinks Kendall is gorgeous but as far as bodies go, Kylie definitely thinks she has a better bu**," the source added.

"She has always looked up to Kim and wanted a body like hers and now she has it! Now with Kim and Kourtney having babies and Kendall having more of the skinny model type body, Kylie thinks she has the best body in the family."
