In the early hours of Saturday live feeds on July 27, 2025, the Big Brother season 27 cameras captured a backyard conversation between houseguests Keanu and Rylie. The discussion turned serious when both accused returning player and Big Brother 13 winner Rachel Reilly of attempting to cheat.According to Keanu, Rachel had allegedly written notes before the Head of Household (HOH) competition."That’s wild, bro! I looked too! She was writing notes!” he said.Note-taking during the game was not allowed, and their claims suggested a possible rule violation involving cards used in the upcoming challenge.Rachel is accused of writing notes before the HOH competition on Big Brother 27Houseguests consider Rachel the bigger threatThe exchange began with Keanu and Rylie discussing Katherine’s status in the game. Keanu pointed out that while he knew Rylie liked her personally, she had to be evicted because she didn’t engage in strategic discussions with anyone. Rylie then redirected the focus by emphasizing that Rachel was "still in the house."Keanu responded, saying that he believed Rachel was alone at the moment and appeared to be "reeling". However, Rylie disagreed and argued that Rachel was "not really alone". They then discussed her earlier alliance, with Keanu highlighting that she once had a group of three, but Ashley quickly left that group after Amy was evicted.As they weighed potential nomination strategies, Rylie concluded:“I think Rachel is a way bigger threat.”Keanu agreed and explained his plan, saying that he would nominate three houseguests and, if one of them used the Power of Veto to save themselves, he would then put "Rachel up" as a replacement nominee. When Rylie suggested a combination of allies, Keanu clarified:“Rachel, Mickey AND Morgan. I would rather nominate Rachel and give her only one chance to get out.”Allegations surface that Rachel wrote notes ahead of the HOH challenge View this post on Instagram Instagram PostThe conversation shifted toward the alleged cheating.
