If those walls could talk!

Brad Pitt — but not his lady friend or six kids — had an audience with the President of the United States at the official Washington, D.C. residence in 2009.

Also paying White House calls since Obama's inauguration: Oprah Winfrey, George Clooney, Denzel Washington, and Serena Williams (not to mention scores of business, civic and political leaders, including Microsoft's Bill Gates and former Vice President Al Gore).

In an unprecedented move, the White House — stressing the administration's commitment to transparency — released a limited list of its visitors since Barack Obama took office, reports. It's the first time any presidential administration has made such a list publicly available.

Clooney visited on Feb. 23 to meet with Obama and Vice President Joe Biden to discuss the ongoing humanitarian crisis in Sudan's Darfur region. Longtime Obama champion Winfrey interviewed First Lady Michelle Obama Feb. 17 and also attended an inaugural reception. (Of Pitt's visit, no details have yet been provided.)

While far from complete (the list is voluntary, not required by law and excludes many for security reasons) the list's 110 names also include Michael Jordan, Michael Moore and Shawn Carter (Jay Z's real name)– but these, MSNBC found, are not the basketball player, filmmaker or hip-hop artist but different individuals with the same names.

More names are expected to be released by the end of this year.
