Warning! The following contains spoilers from the Week 1 Big Brother Head of Household competition. Be sure to tune into the show with your Paramount+ subscription, and read at your own risk!
Big Brother Season 28 is officially underway on the 2026 TV schedule, and we've already got some spoilers ahead of the live feeds starting. Thanks to a longtime BB insider, we now feel relatively certain we know the identity of the Week 1 Head of Household, who also turned out to be the final mystery Houseguest.
As those who watched the premiere may know, only the mystery Houseguests were allowed to compete in the Week 1 HOH competition. This means it was between "two-time Survivor loser" Rick Devens, Season 26 Houseguest Angela Murray and Rachel Reilly. Well, at least it included Rachel Reilly for a minute, until she was pushed into a volcano by a dinosaur.
At the end of the first episode, we were told she would be replaced by another mystery reality tv legend, and now we know who that is thanks to @Hamsterwatch.
Survivor's Dee Valladares Is The Last Mystery Houseguest And The Week 1 HOH
Big Brother went big for its final mystery Houseguest, and snagged Survivor Season 45 winner and Season 50 competitor Dee Valladares as its final Houseguest. Dee then competed against Rick and Angela for the HOH, and reportedly ended up winning the Week 1 HOH competition.
There are no details on what the competition is yet at this time, but a chance we could learn about it on the upcoming episode of BB: Unlocked. I'll be tuning in because I'm curious to see how the show changes with Jerry O'Connell as a host, but also because the live feeds will switch on immediately after.
How Will Dee Run Her Week 1 HOH?
If she's planning to try to win Big Brother like she did Survivor, expect to see Dee try to get in tight with at least three other Houseguests and attempt to run the game with a majority alliance. I think Rick and Angela would be obvious allies as the other vets in the game, but given Angela's wild card status and propensity for outbursts, she may look for a more reliable ally.
If we're looking at other people Dee might align with in the Big Brother Season 28 cast, I think another move would be to get in with the three players who just won safety in their respective competitions. Chuk Anyanwu, Rome Seymour, and Jason De Puy cannot be nominated this week, so I think she'd be smart to take advantage of that and try to align with some of the newbies to shield herself.
By the time the live feeds switch on, we should have explicit confirmation Dee won the HOH competition, as well as who all she nominated for eviction. Remember, per the new rules, Dee will have to nominate three Houseguests, and then if one of them wins the veto, a fourth. Also, thanks to the BB Blockbuster, only one of those three is guaranteed to leave this week, so she'll need all the help she can get from allies come Week 2.
I can't wait to see how it all shakes out, and psyched that Sunday's Big Brother episode on CBS is also a 90-minute special. Tune in at 8 p.m. ET to see what Dee decides to do, and get a look at the Have-Not room and see how it measures up to the awful ones of the past.
