Obama's celebrity status may have been a liability during the campaign, but it's a definite plus for the inaugural events. At the inaugural concert on Sunday on the steps of the Lincoln Memorial, over 100,000 fans gathered for a free concert with Beyonce, Bono and Bruce Springsteen performing. Other headliners included Mary J. Blige, Garth Brooks, Sheryl Crow, Josh Groban, John Mellencamp, Usher, Shakira (pictured), James Taylor and Stevie Wonder. In addition, Jamie Foxx, Queen Latifah and Denzel Washington delivered historical readings. Even more celebrities will perform on TV shows after the swearing in on Tuesday at noon. (Photo: WENN)
