Role in the film
In the film, Celia is Anthony Cooper's attractive, but bossy girlfriend. She often told him that in his texts, he'd have to include hearts with a "less than and a three" or an "XOXO". During a phone call, she hung up after hearing him trash-talking to Alexander while assuming that insults were aimed at her. The next day, she forgave Anthony about the night before and decided to go to the prom with him.
At one point in the film, Celia tried to call Anthony while he was taking his driver's test, which resulted in him failing and the van being totaled. When he picked her up, she was displeased about him failing the test, having to ride in the same van as his family, and having to eat at Nagamaki. In the end, she gets stood up after realizing that she wasn't as important as his family and that it was only the junior prom. While angered by this, she gets in her friend's car and attends herself.
