Meet Oprah Winfrey's new best friend: Tina Fey. NBC has confirmed Winfrey last Saturday taped an upcoming episode of "30 Rock" to air Nov. 6.
"Oprah is very funny in the episode, and we are beyond grateful to have her. Also, I would like to announce that we are officially best friends," Fey said.
You might remember Fey launched a campaign in March, saying it was her goal to become Winfrey's new best friend.
The two spoke about a possible appearance on the NBC comedy when Fey appeared on Winfrey's show in April while promoting the movie "Baby Mama" with Saturday Night Live co-hort Amy Poehler.
Winfrey pal Jennifer Aniston, who's also guest starring this season on "30 Rock", confirmed the appearance weeks ago that Winfrey would be making an appearance as herself.
