The Big Brother season 27 mystery accomplice has been revealed!

Ahead of Sunday’s episode, we found out that one of the houseguests is a secret accomplice inside the house.

A masked figure – “The Mastermind” – revealed that the secret accomplice turned off the lights to allow Rachel Reilly into the house as a contestant, and helped get host Julie Chen briefly kidnapped.

During Thursday’s episode, Mastermind said, “I have had an accomplice this whole time and my accomplice is one of you. If the majority of you can successfully determine who my accomplice is, they will be removed from the house and only 16 of you will be players.”

The house had to vote who they believed the perp was…and they overwhelmingly thought it was Riley. The Mastermind confirmed…Riley is NOT the mystery accomplice!

On Sunday’s episode, we found out…Amy is the accomplice!

Fans on TikTok and X immediately thought Amy could be the secret accomplice….and they were right!

Amy clearly has something in her pocket in the premiere episode. Fans clocked that Amy seemed to be doing SOMETHING with her hand when the lights went out in the BB house, prompting speculation that she was holding a remote that could have turned the power off.

She confirmed it was her the whole time, using the remote to hide the relic once the lights went out. She also started the countdown clock and pulled a lever to let 16th houseguest Rachel Reilly into the house!

This officially means that Amy will be competing at the 17th houseguest this season.
