It may blow up in her face, but it's just wild enough that it could shake up the house entirely and prove to put her in a much better spot than she's been in the first six weeks.

Big Brother Season 27 Week 6 revealed Rachel Rilley as the new Head of Household. With that, she shocked everyone after teaming up with fellow housemate Keanu.
