White House celebrity visitors: Which showbiz stars have the pull to get a meeting? Beyonce, Brad, Oprah (Getty Images; Associated Press) Demi Moore scored a meeting with Valerie Jarrett, which isn't easy. Rashida Jones got a tour of the place from Jon Favreau, her speechwriter ex-boyfriend. Brad and Angelina met the president in the Oval Office, as did George Clooney , but you knew that. And public records indicate that only one person with the first name "Beyoncé" has visited the White House during the Obama years - and Ms. Knowles has been cleared for entry twice.

Many celebs come to D.C. with a cause; only a few have the pull to get into the executive mansion. Which ones? Affleck testifying on the Hill last spring. (Saul Loeb/AFP/Getty Images) Both Robin Wright and Ben Affleck, to talk about the Congo on separate visits with high-ranking staffers last spring. Geena Davis, whose thing is gender equality, got in to see Jarrett in April 2011 and Tina Tchen in September. Jarrett also granted face time to Djimon Hounsou, when he was talking about the global food crisis. Starlet Hayden Panettiere didn't bluff us at the gates of the White House last fall - the visitor log shows she really was in there with top aides, saving the whales. Not on the list: many, many other visiting celebvocates. Not Danica Patrick or Bob Barker or Mark Ruffalo, as far as we could see. Doesn't mean they got turned down; perhaps they were too busy to try. For all his energetic arts advocacy, we found Alec Baldwin in no private meeting, just in a mob of a couple hundred VIPs at a 2009 Kennedy Center Honors reception. Jessica Simpson (Mario Anzuoni/Reuters) How many times has Oprah visited? At least five, so far as we can tell - which is one more than Spielberg. A good time to stargaze at 1600 Penn? Late April, early May, when all the showbiz folks gracing the White House Correspondents" Dinner call in their chits to get a meeting or a tour: Sean Penn last year, Jessica Simpson and Kristin Davis the year before. Meanwhile, for those of you wondering what, exactly, Kal Penn was doing during his months on the Obama payroll, rest assured he was busy: The actor-turned-Office of Public Engagement staffer was a meeting-having maniac, greeting some 1,390 visitors in his less than two years. Dylan gets the Medal of Freedom from Obama Tuesday. (Jason Reed/Reuters) Note: Can't find Brad Pitt? He sometimes signs in as Bradley Pitt, sometimes as William. Stars can be tricky that way. For now, the White House has only released the logs through January - so we'll have to wait to see if a certain Medal of Freedom honoree was logged as Robert Zimmerman - or Bob Dylan.
