Kylie & Tyga We're Back!

Kylie and Tyga hooked up recently in Jamaica ... but they're not getting back together, or at least that's what they're telling their friends.

Kylie flew down to JA for Tyga's music video shoot -- she's not in it, she was just there to lend her support. Even though Kylie posted a pic of herself on a bed down there -- and it was Tyga's bed -- we're told they really are "just friends."
Kylie's been getting very close to PartyNextDoor, but we're told she and Tyga still text constantly, and she's even gone over to his house a few times.
As one source puts it ... there's still a lot of love, and no bitterness since no one cheated -- so they're cool with being pals. For now.
