Kylie Jenner showed off her impressive abs and enviable curves in her latest bikini selfie which she shared via Instagram on Sunday Aug. 2.

The snap, which she took in the bathroom mirror after changing into her bikini, shows off the 17-year-old's perfect physique as she poses in a tiny black bikini, accessorized with an array of gold bangles, while displaying her long manicured talons.

The photograph was taken just before she and sister Kourtney Kardashian, 36, took a break from the hot August sunshine by taking a dip in the pool. "Kourt & Ky swim session," the youngest Keeping Up With the Kardashians star captioned the photo.

Jenner turns 18 on Monday, August 10 and is celebrating by holding a party in Montreal, Canada the following weekend, where she can make the most of the Canadian drinking age.

A couple of hours after posting the sexy bikini snap, Kylie posted another bikini photo to her Instagram account — this one the official flyer for her birthday party on Sunday, Aug. 16.

"Hello Canada. My birthday is coming up & well thank you @team.productions and @oli_beachclub for having me in to celebrate – can't wait to party at #beachclub #montreal #whoismrsmith," the reality star wrote.
