Is former winner Rachel Reilly potentially the mystery houseguest in the Big Brother 27 house?

Big Brother 27 is slated to begin on Thursday, July 10, with an action-packed premiere. While we don't have an official cast list at the time of writing, we have seen plenty of screenshots of the newly decorated BB House. The theme for this season is mystery, with the house renamed to the "Hotel Mystere." As a part of this theme, host Julie Chen-Moonves has teased that several new twists will be introduced throughout the season. One of those twists is a mystery houseguest, and some Big Brother 27 fans have already claimed that a potential 17th houseguest will be former winner, Rachel Reilly.

Could Rachel Reilly be returning in Big Brother 27?

While nothing has been confirmed by Chen-Moonves or CBS, fans have deduced the return of Rachel Reilly from teasers that were posted to promote the new BB season. Specifically, a user on Twitter/X pieced together the puzzle from four teaser images that Big Brother posted in the week leading up to the season's start date.

As you can see from the teaser images and the fans' detective work, it does appear like Rachel Reilly is the mystery houseguest that Big Brother is teasing at. The first image is a clock set to 1:16, which is the exact number of days that Rachel Reilly lasted in the BB House between seasons 12 and 13.

Next, an image of a beach and some corks could hint at Reilly's home in California and her eviction date in BB12 (the corks have 08/13 printed on them, which is the date in 2010 when she was evicted).

The third image has a top hot and a nine of hearts playing card. If we piece together the two hits, they could say "Top 9," which is the place Rachel Reilly placed in BB12. The nine of hearts could also hint at Reilly's love affair with Brendon Villegas, her boyfriend and fiancé on BB12 and BB13 (the two are now married).

Speaking of Brendon, the final image shows the letters "V" and "B" on the bookshelf. This very well could stand for Villegas, Brendon.

Of course, while all of this seems to add up, Big Brother could be hinting at someone else entirely or using some tricks to throw fans off the trail of the real mystery houseguest.

If you're curious about the mystery houseguest, join the club. So far, all we know about the twist is that they are a "polarizing character" and a real person, so someone like Ainsley from BB26 isn't going to be the mystery houseguest. Chen-Moonves talked a little more about the twist in a recent interview, but didn't go into too much detail.

By all accounts, though, the mystery houseguest is likely going to be the 17th houseguest on BB27, joining the 16 new cast members. We already know five of the cast members, but the rest haven't been announced just yet.

So, if this Rachel Reilly theory holds, then the BB13 winner will be joining the Big Brother 27 house sometime during or shortly after the season premiere on July 10.
