We love Betty White and all. We're sure she'll make a funny 30 Rock guest star.

But the fact that show writers spoke to a different celebrity backstage at this year's Emmy Awards has us really excited. According to E! News, a scribe approached Justin Timberlake and said:

"Justin, man, we need to figure out a way to get you on 30 Rock."

The singer's response, reportedly, was positive. How great would that be?!?

Star Alec Baldwin, conversely, was less excited about the idea of bringing Twilight star Robert Pattinson on board. When asked about that possibility, the actor said:

"Uh... I don't know. I'm sure shows like Desperate Housewives want him. There's no shortage of opportunities for him. But our writers don't write for stars, with one exception, and that would be Oprah."

And Timberlake, they hope.
