The multi-talented Nikki Cox expressed an interest in show business at an early age, making her debut dancing in the feature film "Mac and Me." Making her first television appearance at the age of 10 on "Mama's Family," her breakthrough on the small screen came when she starred as Tiffany Malloy on "Unhappily Ever After." Nikki brings her success on television and on the big screen to her role as Mary Connell, childhood confidant and alluring ally to Danny McCoy (Josh Duhamel) in NBC's "Las Vegas." Mary Connell is the Special Events Director at the casino, and a Las Vegas native who has an on-and-off relationship with Danny McCoy. In the first few episodes of the show, her exact role at the Montecito is unclear; her role was rewritten in later episodes to clarify her job title and status. As of the third season she is Hotel Manager of the Montecito.
