Natalie and Nadiya Anderson

Natalie and Nadiya first participated in the 21st season of The Amazing Race, where they called each other "Twinnie". The Andersons won two legs during the season but were eliminated in 4th place in the penultimate leg. They returned in the 24th season All-Stars competition, but were eliminated in the first leg of the season.[5]

Natalie and Nadiya appeared as contestants on Survivor: San Juan del Sur. The twins appeared on a season that used the Blood vs. Water theme, which pitted nine pairs of loved ones against each other. Natalie was placed on the Hunahpu tribe, while Nadiya was on the Coyopa tribe, as the season's theme was pairs of loved ones competing against each other on opposing tribes. Nadiya was the first contestant eliminated from the competition.[6] Natalie remained in the game, making it into the merged Huyopa tribe, and won three reward challenges, one individual immunity, and was sent to Exile Island twice. Natalie ultimately made it into the Final Three and was voted by the jury in a 5–2–1 vote as the Sole Survivor, winning the season's $1,000,000 grand prize.[7]

Natalie was slated to return for Survivor: Game Changers as a member of the Nuku tribe, but she suffered a concussion and was replaced by Sierra Dawn Thomas.[8][9]

For winning Survivor: San Juan del Sur, Natalie returned to compete on Survivor: Winners at War. She was the first person voted out, but inhabited the “Edge of Extinction” island. She spent 33 days on the Edge of Extinction, where she accumulated 16 Fire Tokens, the most any player in the game received. On day 35, Anderson used her 16 tokens to purchase three advantages in the re-entry competition, which helped her win and re-enter the main game. [10] On day 36, she played an idol (purchased on Extinction Island) on herself, which voided 4 votes against her. On day 37, she found an idol and played in on herself, but received no votes. She won the Final Immunity Challenge on day 38, making it to the Final Tribal Council once again. However her gameplay was seen as safe compared to Tony's dominant gameplay, and she finished as the runner up to him in a 12-4-0 vote. Nadiya came to visit her on the loved ones' visit during episode ten.

Natalie competed on the thirty-sixth season of The Challenge.[11] She was initially paired with Wes Bergmann and was voted into elimination in episode one, where she defeated opponent Ashley Mitchell.[12] She was deemed medically unable to continue in the competition, withdrawing in episode 5, after learning that she was pregnant.[13]
