The actress - who played Rebecca Madsen on axed Fox drama Alcatraz - will star as smart and fiery casino worker Mia in new CBS series Vegas.
"Mia is a complete 180 [from Rebecca]," Jones told TV Guide. "She's a lady. She's highly educated. Not that Rebecca wasn't a prodigy in what she did, but Mia went to business school when women weren't going to excel in their studies.
"She's a bit of a princess too. She's mob royalty almost. She's been treated as such, so she's this little kitten until she walks into a board meeting, and then she turns into a tiger."
She added: "What Rebecca and Mia have in common is that if any man gets in their way, they know how to handle them."

Jones explained that she had enjoyed embracing "a new feminine power" on Vegas, which also stars Dennis Quaid and Michael Chiklis.
"I'm really excited to explore that aspect," she said. "I'm trying to get a walk down so I can walk gracefully."
Vegas is based on the true story of Las Vegas sheriff Ralph Lamb (Quaid) and follows his rivalry with gangster Vincent Savino (Chiklis). Jason O'Mara (Terra Nova) and Carrie-Anne Moss (The Matrix) are also among the cast.
Vegas premieres on Tuesday, September 25 at 10/9c on CBS. In the UK, the series will air on Sky Atlantic.
