Prince William and Kate Middleton may unwittingly interfere with the timing of next year’s White House Correspondents’ Association Dinner — again.

The “it” event of the year in the nation’s capital is scheduled for April 25. The Duchess of Cambridge is due to give birth to her second child sometime next April, the royal couple announced Monday.

It’s the second time in four years that the springtime correspondents’ dinner and the princely pair have had some kind of conflict. In 2011, Nerd Prom, as it’s not-so-endearingly called by regulars, was on the same weekend that William and Kate tied the knot in a lavish ceremony at Westminster Abbey.

Although correspondents from across the country were dispatched to cover the wedding, association officials said that the timing of the royal nuptials didn’t affect demand for the dinner.

The Correspondents’ Association hasn't responded to ITK's request for comment on the latest royal-family-related scheduling snafu.
