VIDEO: DAVID LETTERMAN Plays Cruel April Fool's Prank on Guest Kristin Chenoweth

Kristin Chenoweth stopped by last night's LATE SHOW on CBS and became the victim of a rather cruel April Fool's prank devised by the late night host.

The actress was speaking about her horrible ordeal last year in which a lighting fixture fell on her while filming an episode of CBS's "The Good Wife." "No matter where I'm at, I always look up. Because I wanna know, you know, if anything's gonna fall," Chenoweth explained. "Well, sure," sympathized Letterman, just before a sandbag dropped on to his desk just a few feet from the startled star.

After crossing herself, the good-natured belter admitted, "I'm sweating in between my cleavage!" Watch the stunt below and check out Chenoweth's impromptu performance of 'Over the Rainbow' later in the show here!

Emmy and Tony Award winner Kristin Chenoweth effortlessly transitions between stage, television, and film as well as having an accomplished singing career. She received rave reviews while starring in the ABC series Pushing Daisies, for which she received an Emmy Award for Best Supporting Actress in a Comedy Series. She has appeared in Fox's comedy Glee and also starred as Annabeth Schott on the hit drama The West Wing. Ms. Chenoweth received a Tony Award for Best Supporting Actress for her performance as Sally Brown in You're A Good Man, Charlie Brown and received a Tony Award nomination for Best Leading Actress for originating the role of Glinda in Wicked. A Little Bit Wicked, the uplifting chronicle of her life thus far, was released by Simon & Schuster in April 2009 and debuted at number twelve on The New York Times Best Sellers list.

A veteran of the concert scene, Ms. Chenoweth has had numerous collaborations with various symphonies, including the New York Philharmonic, Boston Pops, National Symphony Orchestra, the Chicago Symphony Orchestra, and the San Francisco Symphony. She performed Bernstein's Candide at Lincoln Center with the New York Philharmonic, which was broadcast as part of PBS's Great Performances. Other notable concert engagements include her sold-out Los Angeles solo debut at the Walt Disney Concert Hall, an evening at The Greek Theatre in Los Angeles, theWashington National Opera's 50th Anniversary Gala with Plácido Domingo, and performances at the Hollywood Bowland The Metropolitan Opera. Last year, Ms. Chenoweth presented a sold-out solo show at Lincoln Center's Allen Room in a program entitled Kristin Chenoweth: The Dames of Broadway... All of 'Em!!!, which also aired on PBSstations. She recently made her Australian national touring debut, headlining the 2013 Adelaide Cabaret Festival and performing at the Sydney Opera House.
