She's not as big of a name as Oprah Winfrey - but who is?

Betty White will portray herself on an episode of 30 Rock this fall. The former Golden Girls star joins a long line of guest stars on the sitcom that's included Oprah, Steve Martin, Elaine Stritch, Alan Alda, Tim Conway, Megan Mullally and Jennifer Aniston.

Said Alec Baldwin of the casting decision:

"We all put names in a hat, and we took a vote - if you could have one guest star for the whole season, who would it be. And Betty White was the winner."

The new season of 30 Rock premieres on October 15. Baldwin's Jack Donaghy might get married at some point during it.
