As a part of Project DNA, she switched places in the Big Brother House with her identical twin sister, Natalie Carroll, for the first four weeks, and because they pulled off their deception, Natalie was let into the house to play her own game. In Week 6, Adria won Head of Household and nominated her former ally Will along with Marvin as a pawn, going against the Pinky Swear Alliance. She won the Power of Veto that week and kept the nominations the same. At the eviction ceremony, the vote came to a tie, and she voted to evict Will. This came back to haunt her as she was nominated against her sister in Week 7 by Nakomis Dedmon, but she won the Veto. However, her sister was evicted. The next week, she was nominated by Marvin for being a strong competitor, and when she failed to win the Veto, she was evicted in a unanimous 4-0 vote, placing 7th and becoming the third member of the Jury.
