Linkletter appeared in Cycle 5 of the show after auditioning for the show at the Mall of America. In the final judging, the judges selected Linkletter over the runner-up Nik Pace.
Tyra said of Linkletter, "...she has the model 'thing' more than any of our other winners " the body type, the face type and the attitude,...... She reminds me of the girls I modeled with when I was in Europe when I was 17 years old." Fellow judges Twiggy and Nigel Barker likened Linkletter's look to that of an "English rose". Although she had some of the best photos of the whole competition, she often did not receive as much recognition as some of the other contestants because of her seemingly "sour" facade and not breaking from pretty to beautiful in her photos.
Linkletter graduated from Grand Forks Red River High School in 2003, and attended the University of North Dakota in Grand Forks and St. Cloud State University in St. Cloud, Minnesota as a marketing major; she is currently attending California State University Northridge.
