"Big Brother" Season 27 contestants better grab a life vest, because star Rachel Reilly is checking in as the 17th houseguest

It's also worth noting that when CinemaBlend spoke to Rachel back in 2021, she was eager to play Big Brother again. Fans may remember she wanted to be a part of Season 22's second All-Stars season, but was not able to play because she was pregnant at the time. Now, it would appear she's playing the game again, but for how long is anyone's guess.

"Big Brother" is set to premiere this week. For Season 27 of the hit reality competition series, the official theme will be "Big Brother: A Summer of Mystery," CBS confirmed Wednesday, July 2.
