"Saturday Night Live" comics will celebrate Tina Fey as she receives the nation's top humor prize at the Kennedy Center in Washington.
Also honoring Fey on Tuesday evening will be Steve Martin, Jennifer Hudson, Steve Carell and Jon Hamm.
At 40, Fey will be the youngest honoree to receive the Mark Twain Prize for American Humor since its creation in 1998. She's the third woman to receive the honor after Lily Tomlin and Whoopi Goldberg.
When the prize was announced, Fey hinted she didn't feel worthy. She said she assumed Betty White was disqualified "for steroid use."
Organizers said Fey made her mark as the first female head writer on "SNL."
The show will be broadcast nationally Sunday on PBS.
