Carla Santini is the main antagonist of Confessions of a Teenage Drama Queen. She i the most popular student in school and the enemy of Mary "Lola" Cep.
She was portrayed by the award-winning actress, Megan Fox, who also known for her portrayal as Jennifer Check.
Lola was chosen over Carla to play Eliza in the school play called "Eliza Rocks", and Carla promises to make her life miserable. Lola also beats Carla on a dancing video game at an arcade, where Carla reveals that she has tickets to the farewell concert of Sidarthar, who recently decided to break up. At the party Carla sees Ella and Lola and looks upset.
Back at school, Carla humiliates Lola by denying that she saw Lola or Ella at the party and calling Lola a liar. None of the other students believe Lola's story about being arrested with Stu and leaving her necklace at his house. At the play, Lola arrives backstage just in time to prevent Carla from taking over her part. The modernist interpretation of My Fair Lady (Eliza Rocks) ensues. After a great performance that brings a standing ovation, the cast goes to an after-party at Carla's house.
When Stu shows up to give Lola her necklace back Carla tries to save herself from humiliation by saying he is there to see her, but is proved wrong when Stu gives Lola her necklace in front of everyone. As Carla's lies become apparent, she backs away from the crowd on the verge of tears and falls into a fountain, greeted by everyone's laughter. In a conciliatory gesture, Lola helps her up, and Carla accepts defeat.
