Beyonce and Katy Perry may have some company Tuesday; according to sources Lady Gaga has also been tapped to perform at the Inaugural Ball.

A source tells the Associated Press that Gaga would be performing, but asked for anonymity because that person was not authorized to publicly announce the information.

The Inaugural Ball is a private affair held for President Obama's staffers. Jay-Z was among the performers for the 2009 ball.
