THE SCREENING ROOM: Our Favorite Moments From Tony Winner and "GCB" Star Kristin Chenoweth (Video)

Tony and Emmy Award winner Kristin Chenoweth, who recently announced dates for her concert tour, stars as Carlene Cockburn in the new ABC television series "GCB," which debuted March 4.

The performer, who also said that her next Broadway project will be a revival of On the Twentieth Century, recently tweeted that she would like to take on roles in the Jerry Herman musicals Mame and Hello, Dolly!

With all of the buzz that currently surrounds Chenoweth, we thought we'd share our favorite moments—both on and off stage—from the Tony winner.

Chenoweth took home the 1999 Tony Award for Best Featured Actress in a Musical for her performance in You're a Good Man, Charlie Brown. Chenoweth, who played the role of Sally, sang "My New Philosophy" at the Tonys and accepted the award following her performance.

At the 2010 Tony Awards Chenoweth presented with Promises, Promises co-star Sean Hayes. Who can forget her mock faint when she learned she was not Tony-nominated or her show-stopping kiss with Hayes?

In the 2010 revival of Promises, Promises Chenoweth played the role of Fran Kubelik. Here is a clip of her singing "A House is Not a Home" from Promises, which features music by Burt Bacharach and lyrics by Hal David.

At the 80th Academy Awards, which was held in Los Angeles in February 2008, Chenoweth performed "That's How You Know" from the movie "Enchanted."

Over the years, the singer made multiple appearances on Ellen DeGeneres' talk show. On the "Ellen" musical edition broadcast, Chenoweth appeared as DeGeneres' "Musical Fairy Godmother."

One of Chenoweth's signature tunes, the touching "Taylor the Latte Boy" by Marcy Heisler and Zina Goldrich.

“The Girl from 14G” by Thoroughly Modern Millie composer Jeanine Tesori demonstrates Chenoweth's  extremely extensive range. She often uses the piece in her solo concert appearances.

Here, Chenoweth pays tribute to Oprah with "For Good" from the Stephen Schwartz musical Wicked. In that musical she originated the role of Glinda and received a Tony nomination for her performance.

Chenoweth's new album "Some Lessons Learned," which was released in September 2011, featured her single "I Want Somebody." Here is the music video for that song:

Also on her new solo CD is the heartfelt ballad "Fathers and Daughters."

When Chenoweth made an appearance on the Broadway week of "Dancing With the Stars," she sang "Maybe This Time" from Cabaret—a song she also covered on "Glee"—and "I Could Have Danced All Night" from My Fair Lady.

On Chenoweth's recent appearance on "The Rosie Show," she shared an emotional moment with Rosie O'Donnell, opening up about her adoption.

Aside from Broadway, film and television, the Tony winner has also been seen at multiple sporting events—singing, of course. Here is her rendition of the National Anthem.
