WASHINGTON (AP) -- Watch out Beyonce and Katy Perry. There's another diva set to perform during the inauguration festivities - Lady Gaga.

A person familiar with the inauguration tells The Associated Press that the pop star will perform at Tuesday's ball for White House staffers.

The source spoke on condition of anonymity because that person wasn't authorized to publicly reveal the information.

The staff ball is typically a private affair. During the last inauguration festivities, Jay-Z reportedly performed at it.

According to one attendee, Jay-Z rapped a riff on one of his hit songs, "99 Problems but George Bush Ain't One," to the delight of the throngs of young staffers who worked to elect Obama in 2008.
