After making an appearance at Children's Hospital LA together on Monday, the 17-year-old shared this sexy snapshot with the rapper.
Of course, she tried to play coy and not show his face, but unless someone else has the same "Pasionaye" tattoo on the side of their neck, we're pretty sure it's him.
For what it's worth, the pair has denied any romantic connection, with Tyga telling Vibe magazine in October that he's known the whole family for years.
"I hang out with her [Kylie], her sister [Kendall], I hang out with Scott [Disick] sometimes, I hang out with Khloe sometimes. But people wanna take the situation [with Kylie] to the next level," he said.
Of course, that doesn't exactly explain photos like this one, where it totally looks like they're more than friends, but it's possible that they're not even sure what they are right now, which makes it super awkward when you have to give a "yes or no" answer to the media.
Do you guys think Kylie and Tyga are an item?
