Posting revealing Instagram photos must run in the family.

Following in the footsteps of older sisters Kim Kardashian, Khloe, Kourtney and even Kendall, Kylie Jenner is the latest in the Kardashian clan to trade skin for Instagram "likes" -- slipping into a black two-piece for a brand new pic.

Presented without caption, the photo shows the 16-year-old in a belted bikini.

The teen's Instagram page has been the focus of scrutiny for some time now, with rumors of plastic surgery and lip injections continuing to find traction, no matter how many times she shuts them down.

Last week she also had to blast rumors she hooked up with Jaden Smith at her sister Kim's wedding to Kanye West, tweeting out about reports they were making out at the reception.

"Wasn't caught making out with anyone at my sisters wedding lol," she wrote. "Jadens a close friend of mine."

It's pretty crazy to see Kylie grow up in front of our very eyes, as she was just a kid when "Keeping Up with the Kardashians" debuted in 2007. They get big so fast!
