As previously noted in Celebritology, Tom Hanks, Nicole Kidman, Jack Black, Jennifer Lopez and Marc Anthony are expected to attend. People also notes that Barbra Streisand and husband James Brolin will be there, as will Chris Evans (it’s only right that Captain America should welcome the royals), Judd Apatow, Jason Bateman, director Jason Reitman, Zooey Deschanel and Ed Helms, among others. (The Hollywood Reporter adds that Quentin Tarantino will be on hand as well.)

This is easily the best news I’ve heard all week. As a huge fan of Galifianakis and his say-whatever-comes-to-mind style, he’s the star most likely to make the gala interesting, assuming that People is right and he really will be there. (I reached out to a rep for Galifianakis to get confirmation but have not heard back yet.)

A conversation between Galifianakis and the royal newlyweds has so much potential. For example ...

He could say something irreverent and totally Galifianakis-like during their initial introduction.

You know, something like, “It’s so nice to meet you. I loved you both in that Disney movie about the princess. You look so different in person, though.”

The BAFTA Gala could turn into an episode of “Between Two Ferns.”

Here’s hoping Galifianakis can clear out some space, set up a couple of cameras, a few chairs and a strategically placed pair of plants and conduct the most epic “Ferns” interview ever with the royals.

He could put his arms around Kate and William and start singing this song from “The Hangover.”

If he does, I sincerely hope it gets filmed and posted on YouTube.

He could bring his twin brother Seth Galifianakis to the gala.

I feel like Seth would get along really well with Kate Middleton. For starters, their fashion sensibilities are remarkably similar.

He could spontaneously strip off his tuxedo and perform “Tomorrow” in his “Annie” garb.

And if he does, Kate and William will be so charmed, they’ll never go back to England. Guaranteed.
