Which Oscar-Nominated Screenwriter Saw Ke$ha Perform at MSG?

Walking through the foggy streets of Manhattan late Wednesday afternoon, you couldn't help but notice the hordes of glitter-covered teenage girls roaming the streets, waiting for the Ke$ha concert at Madison Square Garden to begin. Which Oscar-nominated screenwriter was also present at the World's Greatest Arena for the spirit-hooded madness?

Nora Ephron, obviously. EW reports that Ephron and her ex-husband Carl Bernstein (yep, that Carl Bernstein) were spotted at the concert -- though presumably neither brushed their teeth with a bottle of Jack beforehand.

Apparently, the pair were in attendance, separately, to support their Max -- a guitar player for the pop singer. Let's hope neither were harmed when Ke$ha fired a glitter cannon into the audience during her performance of "Blow."
