The small heart appeared on the back of her upper arm shortly after her 18th birthday and since Kylie usually keeps her fans informed of any new piercings, hair colors and other things like that (often times live on Snapchat), a lot of people thought it was probably just temporary. Kylie and her sister Kendall Jenner used to get Sharpie tattoos by an artist friend that looked REALLY convincing, so people thought it was just something like that.
Turns out, it is real, and while some speculated that the heart was for Tyga, it's actually a BFF tattoo that she got with four of her closest pals.
"Lil babies in NY. 3/5 of the tats," she captioned the photo, which she didn't tag any of her friends in, but we did a little digging and we were able to figure out who these two tattoos belong to.
One of them is Justine Skye, who Kylie was hanging out with last night, and who shared this picture on her Instagram recently, where her tatt can clearly be seen:
The other belongs to Kylie's friend Anastasia Karanikolaou, who shared this pic on Instagram a few weeks ago, where her heart ink is visible:
As for the other two tattoos, we're not sure who they belong to. Kylie's squad has more than five people, so it's tough to narrow it down and we haven't seen any ink on any of the other members of her inner circle.
It's possible that the other two belong to Kendall Jenner and Hailey Baldwin, who also just got friendship heart tattoos, but we're not 100% sure on that one because they both got broken hearts, so it could just be a coincidence.
