The new ABC series will make its premiere March 4 at 10 PM ET on ABC. On "Chelsea Lately," the Tony winner chats with Handler about her character on "GCB," Carlene Cockburn.

Based on Kim Gatlin's book "Good Christian Bitches," the series is described as such: "Amanda Vaughn (Leslie Bibb), once the ultimate high school 'mean girl,' is forced to return home in disgrace after her marriage ends in scandal. Amanda is nothing like the girl she was 20 years ago, but as her old classmates reacquaint themselves with the new Amanda, will her home town welcome her with open arms or seek revenge? No one in this town is a saint, but that doesn't mean they can't have a heart. As Amanda and her teenage kids try to adjust to their new lives, the ladies from her past alternate between sympathy and scheming."

Chenoweth won the Tony Award in 1999 for her performance in You're A Good Man, Charlie Brown. She was nominated in 2004 for her performance in Wicked and has also been seen on Broadway in Steel Pier, Epic Proportions and The Apple Tree.
