President Barack Obama's second inauguration is shaping up to be one of the hottest tickets of the year.

Two days after the Presidential Inaugural Committee announced that Beyonce, Kelly Clarkson, and James Taylor would perform at the official ceremony on the West Front of the U.S. Capitol in Washington, D.C., several other celebs have been added to the weekend's star-studded lineup.

The committee announced Friday, Jan. 11, that Alicia Keys, Brad Paisley, Katy Perry, John Legend, fun, Stevie Wonder, and Usher would be among those on hand at the Kids' Inaugural Concert on Saturday, Jan. 19, and at the official Inaugural balls on Monday, Jan. 21. Marc Anthony, Nick Cannon, Smokey Robinson, and members of the cast of Glee are also expected to make appearances.

"We are honored and excited to have such a diverse, talented group of musical guests joining Americans from across the country to celebrate the 57th Inauguration," Presidential Inaugural Committee CEO Steve Kerrigan said in a statement.

"Vice President [Joe] Biden and I are honored to have these wonderfully talented musical artists perform at the Inaugural ceremony," Obama, 51, said in a statement after the committee announced Beyonce, Clarkson, and Taylor's participation. "Their music is often at the heart of the American story and speaks to folks across the country."

The Kids' Inaugural Concert on Jan. 19 carries on a tradition started by First Lady Michelle Obama and Dr. Jill Biden in 2009 that builds on initiatives to support military families. Monday's official balls also honor servicemen and women; the Commander-in-Chief's Ball will include both active duty and reserve military, as well as Medal of Honor recipients and wounded warriors.
