Annie Wilson And Naomi Clark, 90210
In the reboot of 90210, Annie Wilson and Naomi Clark are the resident frenemies in the show, and their delicate relationship is full of drama, rivalry, and betrayal. In just the first season, the two pals have a tense year where Annie, the local nice girl, stole Naomi's boyfriend by not-so-secretly developing feelings for him and then kissing him behind her back at the homecoming dance. Not exactly BFF material.
