President Obama's second presidential inauguration may not draw the kinds of crowds that came for the first go-round, but it certainly won't lack for star power: Among the performers at various inaugural festivities - including official galas on the Jan. 21 and a children's concert on the Jan. 19 -- include Katy Perry, Alicia Keys, Smokey Robinson, Stevie Wonder, Marc Anthony, and John Legend. Usher, Brad Paisley, and the cast of "Glee" are also slated to perform, along with a number of other performers.

Beyonce, Kelly Clarkson, and James Taylor have already been announced as the performers at the inaugural signing ceremony.

• Beyonce, Kelly Clarkson to perform at Obama's inauguration
• Obama's second inauguration will pale in comparison to first

The inauguration's two official galas, The Inaugural Ball and the Commander In Chief's Ball, are expected to draw nearly 40,000 people combined. Both balls will be held at the Washington Convention Center on Jan. 21.

It hasn't yet been announced which stars will sing at which balls.

Is it true Republican officials will be welcomed at the inauguration's two official balls, as they have none of their own this year?
