The “Love Island USA” villa is full of double standards … at least according to one of the most recent contestants — who felt she was on the receiving end of sexist attitudes.

Here’s the deal … Kenzie Annis — who appeared on Season 8 of the hit show — sat down with Alex Cooper on the “Call Her Daddy” podcast … and they discussed her costars’ reactions to her making out with Corbin while she was coupled up with Caleb, a revelation discovered by the group during the “Movie Night” episode where Islanders watch clips of themselves the audience has seen.

Kenzie was torched for stringing multiple men along … but when the group found out a male contestant named Sincere Rhea was with two women, Sol and Melanie, at the same time — and eventually Amora from Casa Amor — they didn’t attack him with nearly the same vigor.

She feels Sincere actually lied … and she says she didn’t make any fake promises — instead trying her hardest to be open and honest throughout the entire experience.

Ultimately, Kenzie says she feels she and Sincere were held to different standards … and she thinks gender has a lot to do with it.

Worth noting … Kenzie was dumped on the island — while Sincere finished third with partner Melanie.
