Mekia Cox cast in NBC's 'Undercovers'

Replaces Jessica Parker Kennedy on J.J. Abrams series

Mekia Cox has been cast in NBC's spy drama "Undercovers."

Cox will replace Jessica Parker Kennedy on the highly anticipated J.J. Abrams series. She'll play Lizzy, the older sister of the female lead, who is unaware of her family's involvement in the CIA.

Mekia was most recently seen on The CW's "90210" and in the Michael Jackson documentary "This Is It." She's repped by Global Artists Agency and A Management.

"Undercovers" is produced by Warner Bros. and Bad Robot and is considered one of NBC's frontrunners in the fall.
