Demi. She praises her all the time on X Factor and she even dresses herself like Kelly quite often. Her music is also obviously inspired by her: Kelly's My December --> Demi's Remember December.
No shade though. I can understand why people would want to copy Queen Kelly.
In relation, Demi Lovato, Taylor Swift and Miley Cyrus
all copied Selena Gomez into Movies. Granted
they were never as successful as Selena's but it
was certainly a good effort. B-
