She plays Samantha Bloom’s (Gugu Mbatha-Raw) sister, Lizzy Gilliam. She replaced Jessica Parker Kennedy, who played the part in the pilot. Cox says the transition wasn’t too bad.

“I came in and everyone was so super nice,” she tells Zap2it. “Immediately, it felt like family. [Parker Kennedy] was a great girl, as well. They loved her too, but they still welcomed me with open arms, which I was very thankful for.”

Viewers may recall Cox from her stint as Sasha on “90210,” which, as we reported first, she’ll be reprising in Season 3. But, you may also be surprised to hear that Cox is a pretty accomplished dancer and she danced with Michael Jackson on the documentary, “This Is It.”

You’d think after scoring a gig with the prince of pop that Cox could handle any audition, but she tells us she was really nervous about meeting “Undercovers” executive producer, J.J. Abrams, the man behind “Lost” and “Alias.”

“[Abrams] is just such a down to earth person that all those nerves just went away,” she says. “I had maybe one of the best auditions I feel I’ve had. And, I think it’s because of his energy. He gives off such amazing energy and it allows you to be good at what you do.”

Dixon probably thought he was rid of her after finding out that she was faking her pregnancy and he kicked her to the curb, but now Zap2it exclusively learns that Sasha and all her crazy will be back.

A CW spokesperson confirms that Cox will reprise her role as Sasha in Season 3 and she’ll be rocking Dixon’s (Tristan Wilds) world.
