The 17-year-old reality star snapped the mirror selfie before hitting the pool with older sister Kourtney Kardashian, 36. Sounds like a fun sister day!
“Kourt & Ky swim session,” she captioned the photo.
Kylie is getting ready for her big 18th birthday on August 10 where she will be celebrating with friends by hosting a party in Montreal, Canada.
Happy early birthday, Kylie!
