First Day Of Summer 2013 Brings Out Kendall Jenner's Swimsuit (VIDEO, PHOTO)

What Kimye baby?

Kim Kardashian's baby sis Kendall Jenner is slowly but surely taking over as Kardashian Klan Daughter No. 1 by posting sizzling Instagram pics of herself in a swimsuit, just in time for the first day of summer 2013.

The 17-year-old showed off her modelling skills on Thursday in a sexy one-piece swimsuit. The reality star wannabe captioned the photo: "some un-retouched shots from today's shoot with @adamfranzino. styling by @myangelica." Only a teenager could brag about looking good in a photo without airbrushing.

It's no wonder the budding Paris Hilton isn't afraid to show off her bathing suit bod; Kendall recently revealed that she doesn't like chocolate! (Hmmm, does Jenner have the secret to staying svelte?)

The second-youngest Kardashian is rivalling big sis Kim's love of taking selfies; in June alone she took a pic of her bejewelled tummy, a makeup collage and a racy bikini shot.

We smell a new reality series on the horizon!
