Everything we know about the Islanders on ‘Love Island USA’

Love Island hit the UK in 2015 and quickly turned into must-watch summer television, pulling in bigger crowds each year with its simple formula: young singles locked inside a villa, forced to couple up or get dumped. The original series set up shop in Mallorca, Spain, and dangled a fifty-thousand-pound prize for the last pair standing.

That British run drew its share of headlines, from claims of scripted drama to serious concerns about editing and contestant welfare. Two former participants later died by suicide. Ratings kept climbing anyway, adding roughly a million viewers per season.

When the format crossed the Atlantic, CBS placed the American edition inside a private villa in Fiji and kept the same rules. Islanders had to form pairs or leave, then survive public votes and challenges for a chance at one hundred thousand dollars. Arielle Vandenberg hosted the run that began airing in July 2019.

The cast started with eleven contestants and grew as new arrivals entered, eventually totaling twenty-five over the course of the season. For anyone who missed the nightly episodes on CBS or CBS All Access, here is a guide to every islander who appeared.

Alana Morrison

Alana came across as the steady, advice-giving presence in the villa, often checking in on Caro. She paired with Yamen early, but that connection ended when she was dumped on day eleven after failing to form a new couple.

Alexandra Stewart

Alexandra stayed low-drama but never short on pointed commentary. She and Dylan formed one of the season’s steadier pairings and finished as runners-up. After the finale the couple split, and Alexandra went on to co-host and produce the After The Island podcast while working as a publicist.

Caro Viehweg

Caro spent much of the season visibly anxious and quick to overthink every twist. She moved from Cashel to Cormac before finishing third with Raymond Gantt. Since the show she has launched the curly-hair brand Alchemy Curls, married Rene Lacad, and welcomed a daughter with a second child expected as of 2026.

Cashel Barnett

Cashel started paired with Caro before switching to Kyra. He later flirted with new arrivals and stayed in the mix until the later weeks. Post-show he competed on The Challenge: USA alongside Kyra Green.

Christen McAllister

Christen arrived later in the run and immediately tested existing couples, most visibly when she asked Yamen on a date. Her short stay kept the villa on edge until she was eliminated.

Cormac Murphy

Cormac earned the early reputation as the villa’s main agitator, openly flirting while paired with Caro. His lack of commitment led to his exit before the finale.

Dylan Curry

Dylan stood out for small, consistent gestures of support toward the group. He and Alexandra reached the final as runners-up, though the pair parted ways shortly after the season ended.

Elizabeth Weber

Elizabeth and Zac formed the season’s most solid couple from early on. They won the finale and split the one-hundred-thousand-dollar prize. The relationship lasted only a few months after the show; Elizabeth got engaged in December 2024.

Katrina Dimaranan

Katrina entered as one of the later additions and quickly built friendly bonds with the guys. Her date with Weston created fresh tension before she left the island.

Kyra Green

Kyra was paired with Cashel after he left Caro. She remained wary of outside flirtations and stayed in the game until the later rounds. After the season she appeared on Ex on the Beach and competed on The Challenge: USA.

Mallory Santic

Mallory leaned into the party-girl role but struggled to build a lasting connection. Weston’s interest in Katrina made her position untenable, and she was dumped before the final week.

Michael Yi

Michael was the first islander sent home. His lack of chemistry with Caro led to his quick exit after he failed to secure a partner.

Weston Richey

Weston started with Mallory and later explored options with Christen and Katrina. His birthday brought new attention, and he ultimately left without a final couple.

Yamen Sanders

Yamen began as a respectful, lighthearted presence and paired with Alana. He accepted a date with Christen, which contributed to Alana’s elimination, and he departed before the finale.

Zac Mirabelli

Zac matched Elizabeth’s steady energy and became the season’s most committed partner. The couple won and split the prize money. They parted in late 2019, and Zac has since worked as a model for several luxury brands.

Winners and Final Placements

Elizabeth Weber and Zac Mirabelli took the season on August 7, 2019, after receiving the most public votes. Dylan Curry and Alexandra Stewart finished second. Caro Viehweg and Raymond Gantt placed third.

What Happened to the Winning Couple

Elizabeth and Zac dated only a few months after filming before splitting in December 2019, citing different long-term goals. Elizabeth later got engaged in December 2024, while Zac has kept a lower profile centered on modeling work.

Post-Show Careers and Reality TV Returns

Alexandra Stewart co-hosts the After The Island podcast and works in publicity. Caro Viehweg runs Alchemy Curls and has appeared on Women Prosper. Several cast members, including Caro, Kyra Green, and Cashel Barnett, later competed on Ex on the Beach or The Challenge: USA.

Long-Term Relationship Outcomes

None of the couples formed during season one remain together as of 2026. The runners-up, Alexandra and Dylan, ended their relationship shortly after the finale, consistent with the pattern seen across the rest of the original cast.
