Ella Simms (Katie Cassidy of 'Harper's Island')
Ella is a stop-at-nothing publicist and diva who looked up to Sydney as a mentor until a betrayal came between them.
"She's the comic relief of the show," Cassidy said. "She's bossy. ... She's outspoken. She's crass. She's very blunt, but then there's a part of her that comes deep down from a complete lack of love."
