It’s not easy to be a celebrity at one of these things, besieged from all sides by fans and distant acquaintances — no, really, that stuff is exhausting! — but the Oscar winner spent the entire dinner posing for photo after photo with every female who could squeeze into a frame with him.

And then he spent the next three hours on his feet — we watched, so we know — schmoozing a parade of VIP guests (Harvey Weinstein, Barbara Walters, Jay Carney) in the front foyer of the Bloomberg/Vanity Fair after party at the French ambassador’s residence, but making it all look like fun.

Why? “If you’re going to commit to do something, you need to do it,” he told us, still going full steam at 2 a.m. In Clooney’s case, that meant talking (mostly election politics) to everyone who approached — and strategically lobbying the people who can help with his pet cause.

Make any progress? He grinned. “Nothing — nothing — gets solved at the Correspondents’ dinner. Ever.”
