In a scheduling conflict of epic proportions for celebrity-spotters, the royal wedding and the White House Correspondents’ Dinner will take place the same weekend!

Prince William and Kate Middleton will say their vows Friday morning in London, in front of loved ones, assorted politicos and celebs, and anyone in the world with a working television or Internet connection. Then, on Saturday is the Hollywood-heavy Correspondents’ Dinner, providing an opportunity for the John Boehners and Justin Biebers to come together in an annual celebration of . . . something.

On a practical level, this means that Washington’s experts in star-gazing and glamour-assessment will be forced to consume copious amounts of caffeine and champagne within a 24-hour period.

On a competitive, cultural level, the back-to-back hype-fests raise a question: In a bejeweled mano-a-mano face-off, which event is more worthy of a celebritologist’s consideration?

The royal wedding seems like the obvious winner, simply because it’s a much rarer occasion and has international interest. But let’s compare the two and find out:

The social showdown of the year — White House Correspondents’ Dinner or royal wedding?

Media coverage: The royal wedding will be covered live and excessively on every major television network and YouTube. The White House Correspondents’ Dinner will be broadcast live and thoroughly on C-Span. Advantage: Royal wedding.

Heads of state: British Prime Minister David Cameron will attend the royal wedding. President Barack Obama will crack jokes at the Correspondents’ Dinner. Advantage: Tie.

Funny famous people:Rowan Atkinson, the British comic best known for his character Mr. Bean, is on the wedding guest list. Confirmed for the Correspondents’ Dinner as of press time: Jane Lynch, Paul Rudd, Mindy Kaling from “The Office,” Jesse Tyler Ferguson and Eric Stonestreet of “Modern Family” and emcee Seth Meyers of “Saturday Night Live.”Advantage: Correspondents’ Dinner.

Pregnant celebrities: Victoria Beckham and soccer-playing husband David Beckham, who are expecting their fourth child this summer, will be front and attention-getting center at Westminster Abbey. Meanwhile, at the dinner, Kate Hudson, also expecting a child this summer, will bring her baby bump — and perhaps British boyfriend and Muse frontman Matthew Bellamy? Advantage: Again, a tie.

British filmmakers: Guy Ritchie, director of “Snatch” and “Sherlock Holmes,” will be at the wedding. Tom Hooper, the director who just won the Academy Award for “The King’s Speech,” has reportedly been invited by Time magazine to the dinner. Advantage: Correspondents’ Dinner.

Potential for fashion scrutiny: After the Correspondents’ Dinner, analysis of first lady Michelle Obama’s ensemble — as well as the ensembles of the movie- and TV-star set — will be part of the post-game analysis. But the royal wedding has The Dress. Advantage: Royal wedding.

And the winner is: Too close to call. So get those champagne flutes and coffee cups washed and ready.
