A second Love Island USA contestant has been removed from the villa after historic social media posts emerged that appeared to show her using a racial slur.

Alannah Keyser was removed after a video showed her apparently lip synching to the n-word in a song, while other screenshots showed her appearing to use the same slur in an Instagram comment and Snap message.

The posts came from a private account and were not made public until after Keyser entered the villa, and were therefore not flagged during broadcaster Peacock's vetting process, sources told US publications including Variety, external.

Keyser, who had appeared on the dating series since Sunday, has been approached for comment.

Keyser joined the series as a "bombshell" during the show's traditional mid-season Casa Amor twist, where new islanders enter the villa to challenge existing relationships.

Before her departure, Keyser appeared in the first 20 minutes of Thursday's episode, conversing with one of the male contestants before appearing briefly in two further non-speaking scenes.

However, the show's narrator then confirmed her exit, telling viewers: "Alannah has left Casa Amor."

It is the second time this season that a contestant has left over the use of racist language, after Vasana Montgomery was removed, external following the announcement of the line-up.

Montgomery was seen appearing to use the n-word in two different videos that were circulated online.

She later said in an Instagram statement: "In those videos, I used a racial slur. There is no excuse for it, and I am deeply sorry.

"I am embarrassed and disappointed by my words. I take full responsibility for what I said and understand why it has hurt and upset people."

Two further contestants were also removed from the seventh series of Love Island last year.

Yulissa Escobar was asked to leave the villa after videos emerged of her using a slur in a podcast.

In a TikTok video, external posted after she was removed, Escobar said: "I get it. I said a word that I should have not said. But I wish I would have never said that. It is what it is. I can't go back in time. I am sorry that I said that word."

During the same season, Cierra Ortega exited after using a racist term for Asian people. She later apologised and said, external that she "genuinely had no idea" that the term she had used was considered a slur.
