The series underwent several casting adjustments for the second half of the first season. Port and Olivia Palermo remained, and the program saw the addition of Port's friend Roxy Olin and Palermo's co-worker Erin Kaplan. The revamped cast remained for the second season, which premiered after the sixth season of "The Hills" on April 27, 2010. The season documented the deterioration of Port and Olin's friendship, which culminated with the latter moving out of their shared apartment. The season concluded on July 13, 2010, the same evening as the series finale of "The Hills".
