JaNa Craig and Kenny Rodriguez — two stars from season 6 of “Love Island USA” — are through … TMZ has learned.

Sources familiar with the situation tell TMZ … JaNa and Kenny broke up Sunday morning — with Craig ultimately making the choice to end the relationship.

We’re told it’s not yet clear what led to the split … but, JaNa’s been leaning on her close girlfriends all day to help her get through her heartbreak.

Online speculation about the couple’s breakup has spread over the last few days … after eagle-eyed fans noticed JaNa and Kenny took one another out of their Instagram bios and stopped following each other.

JaNa’s close friends Serena Page and Leah Kateb — known collectively as “PPG,” short for “Powerpuff Girls” on the show — unfollowed Kenny as did their significant others.

In fact, it seems they had all their friends unfollow the other person … even though they were posting about one another on social media last night — so, this seems like some sort of major blowup occurred.

JaNa and Kenny finished in third place in the competition last year … with Kenny coming into the Villa on Day 13. Serena and her beau Kordell Page ultimately took home the $100K prize.

We reached out to reps for the contestants … so far, no word back.
