Dee Valladares Joins Big Brother 28 After an Impressive Reality TV Career
Before entering the Big Brother 28 house, Dee Valladares had already established herself as one of CBS reality television’s most recognizable competitors.
Born Dianelys Maria “Dee” Valladares in Havana, Cuba, the 29-year-old entrepreneur was raised in Hialeah, Florida, and later founded the backpack and travel company Wanaroam. While successful in business, she became widely known after winning Survivor 45, making history as the first Cuban-born Sole Survivor.
Her reality television journey has continued to grow ever since.

How Fans Figured Out Dee Valladares Was the Mystery Survivor Alum on Big Brother 28
Long before official confirmation arrived, fans had already begun connecting several carefully placed clues.
The biggest hint came during the Big Brother 28 premiere, which introduced the season’s “Time Trip” theme. Following Rachel Reilly’s dramatic early elimination during a Jurassic Period challenge, host Julie Chen announced she would travel through time to find a replacement.
She specifically referenced September 27, 2023—the exact day Dee won Survivor 45.
That single clue immediately sparked widespread speculation that Dee would be entering the game, with many viewers believing she could even become the season’s first Head of Household.
Additional reports strengthened those theories. Entertainment Weekly and other outlets had already revealed Rick Devens as one Survivor crossover while noting that another former Survivor player would also appear. Dee quickly became the leading candidate, especially after her recent appearance on Survivor 50: In the Hands of the Fans.
Hints from respected live-feed source Hamsterwatch, combined with growing discussion across BlueSky and X, only added momentum. As early feeds and cast conversations surfaced, many fans became convinced Dee was indeed the mystery player.
The casting decision also fit Big Brother’s recent strategy of using crossover competitors and returning veterans to generate excitement, particularly during milestone moments like the franchise’s 1,000th episode.
Dee Valladares Makes an Immediate Impact During the Early Days of Big Brother 28
Big Brother 28 premiered on July 9, 2026, launching with 14 new houseguests before introducing surprise veterans and crossover players, bringing the total cast to approximately 16–17 contestants.
Dee wasted little time making her presence felt.
She won the season’s first Head of Household competition, becoming the first Latina HOH since Big Brother 21 while also recording the first competition victory by a Survivor alum in this Big Brother setting.
Early live feeds also showed her doing what many Survivor fans expected—quietly building strategic alliances while positioning herself near the center of the game’s early power structure.
Her arrival, alongside Rick Devens and Angela Murray’s energetic return, has immediately created one of the season’s biggest storylines.
Why Dee Valladares Could Be One of Big Brother 28’s Biggest Threats
Dee enters Big Brother with one of the strongest competitive reputations in the cast.
During Survivor 45, she controlled a dominant alliance, built strong social relationships, made difficult strategic moves when necessary, and showcased her physical ability by winning the final immunity challenge under the new-era format.
She ultimately secured victory with a 5-3-0 jury vote, earning praise for balancing loyalty, strategy and competition success throughout the season.
Although her run on Survivor 50 ended earlier with a 14th-place finish, it further cemented her status as one of the franchise’s modern stars.
Now, with Big Brother 28 only just underway, viewers are watching closely to see whether Dee can translate the calculated, loyal-yet-ruthless style that made her a Survivor champion into another winning reality television campaign. With live feeds only recently beginning, her story is still unfolding, making her one of the season’s most intriguing players to watch.
