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 Wikle along with Marvin Latimer, 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. Adria won the Veto, leading to her sister's eviction. 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.
Adria was the first houseguest in Big Brother US history to win Head of Household, win the Power of Veto, and cast a tiebreaker vote all in the same week, she would be followed by James Zinkand and Nicole Franzel.
Adria is the first female to cast a tiebreaker vote.
Adria is the first houseguest to win three consecutive competitions in a row.
