Kylie Jenner isn't shy about flaunting her body.

Kim Kardashian's little stepsister has been spending plenty of time by the pool this summer, uploading tons of photos of herself and Kendall Jenner baring their bikini bods.

Last month, after spending the Fourth of July in a pink and black two piece with sister Kendall and family friend Jaden Smith at their dad Bruce Jenner's Malibu beach house, the 15-year-old posted a new selfie, showing off her curves in a black bikini (above).

The Keeping Up With the Kardashians star, who turns 16 in August, also posted a cute photo of herself and sister Kendall, holding their puppies. Wearing bikini tops and shorts, the gals posed in the playful pic.

Kylie also utilized social media to set the record straight about her rumored relationship with Jaden, tweeting: "Media always making it seem like I'm dating everyone I'm seen with..Makes no sense to me. Don't listen to everything u see, people."

Kylie and Jaden  made headlines when they were spotted together at a screening of Brad Pitt's World War Z.

After the two were photographed together, Kylie took to her Twitter page to rant about the paparazzi.

"It sickens me that 5 cars of men are legally allowed to follow a 15 year old girl," she wrote. "How is this legally allowed?"

Will Smith's son referred to Jenner as his "friend" in the May issue of Wonderland Magazine. "She's one of my best friends. It's pretty awesome," he gushed.
