- „Who do you think they're going to believe? YOU? Or 'innocent little Emily'?”
- —Cousin Emily[src]
Emily is Annie and Dixon's cousin from Kansas. She comes to L.A. to live with the Wilson family while her mother is in rehab.
All Emily wanted to do was fit in, but when Annie looks down on her instead of accepting her, she attempts to take over Annie's life and manages to act like a total bitch about it. She changes her hair, buys clothes just like Annie's, tries to turn her friends against her and then steals a part that Annie auditions for.
Annie confronts Emily about how she lied to Naomi, Silver, and Adrianna and the resort/spa, but they believe Emily instead of Annie.
Emily has a crush on Liam and attempts to break him and Annie up which works (but they actually faked their break-up to trick her). Then, she acts very sweet and innocent, making Annie's anger look irrational.
Emily's true nature was eventually exposed with a help of Liam Court, pretending to agree to go on a date with her. Liam brought Emily back home after the date for her to start trash talking Naomi, Silver and Adrianna. Little does she know that the girls mentioned are all waiting for in the living room for Emily's "surprise party," hearing every word that she said.
Emily quickly packs her things and leaves town after realizing her two-faced personality has been revealed.
At a West Beverly alumni event, Emily had a brief appearance when Annie sees her at the event. Even though Emily was only there for a couple months, she has come by to brag about how many hits her blog gets and how she has an agent while attending NYU which causes Annie to think about the state of her life and she starts to write a blog as well.
