One 40 years old... the other is 88-and a half.
Comic giants Tina Fey and Betty White will face off against each other at the 62nd Primetime Emmy Awards - each are nominated for Outstanding Guest Actress in a Comedy Series for their separate stints hosting Saturday Night Live.
The Emmy nominees were announced Thursday morning in Los Angeles with both women getting the nod.
White, whose gig hosting SNL was the result of a fan-fueled Facebook campaign, earned the show's highest ratings in 18-months. Fey won the Emmy in this category last year for her Sarah Palin spoof on SNL.
In addition to White and Fey, other notables competing in the same category include Broadway vet Kristin Chenoweth for her hilarious performance on Glee's The Rhodes Not Taken episode, and Glee star Jane Lynch's cameo on an episode of Two And A Half Men. (Lynch was also nominated for Outstanding Supporting Actress in a Comedy Series for her role on Glee).
Also nominated in the 'Guest Actress' category were Christine Baranski for her role on CBS' The Big Bang Theory, and Kathryn Joosten for her appearance on Desperate Housewives.
The winner will be named when the Emmy Awards, hosted by late night funnyman Jimmy Fallon, will be broadcast August 29 on NBC.
