Donald Trump -- star of NBC's birther movement "Celebrity Apprentice" -- decided to show his hair, er, face at the White House Correspondents' Association Dinner on Saturday.

Trump, who began the week taking credit for the White House's decision to release President Obama's birth certificate [4], was promptly booed on arrival.

[6]Trump arrived on the red carpet at Washington’s Hilton Hotel with his wife, Melania, shortly at 7:00 p.m. (ET). After giving a brief interview with a group of several of media outlets, Trump -- who was invited to the event as a guest of the Washington Post -- walked away to a chorus of audible boos from the media members on the press line. (And it wasn't because they wanted to hear Trump talk more.)

Trump's entrance briefly took the spotlight away from the other celebrity arrivals, including Mila Kunis, Scarlett Johansson, Sean Penn, David Arquette, Elizabeth Banks, Erin Andrews, Mira Sorvino, Jeremy Piven and at least one of the Wayans Brothers.

Obama and his wife were scheduled to arrive at the 8 p.m. (ET).

I didn't see New Yorker editor David Remnick -- who earlier this week called Trump a "race-baiting, irrepressible jackass" [8] -- but Zach Galifianakis, Jon Hamm and the Coen Brothers were among the guests invited to sit alongside him at the magazine's table.

However, I did spot Bob Schieffer, who said Trump was guilty of "an ugly strain of racism [9]" on Wednesday's "CBS Evening News."

There was some question whether Trump would attend the dinner at all -- though not because of the still-simmering "birther" controversy. Trump was also scheduled to attend the wedding of fellow real estate mogul (and noted Obama hater) Steve Wynn in Las Vegas on Saturday, and delivered an expletive-filled speech [10] there on Thursday.

I'm guessing there may be more than a few of those muttered at tonight's so-called "nerd prom" -- and plenty of firesworks in store.

Trump told ABC News that he didn't think Obama, who will give a speech at the dinner, would joke about him [11].

But here's hoping Seth Meyers, who is serving as the evening's host, serves Trump some humble pie.
