President-elect Barack Obama is adding a "Youth Ball" to the parties planned to celebrate his Jan. 20 inauguration.

And his inaugural committee said Tuesday that, despite the economic hard times, private donations are pouring in to help cover the costs of the citywide bash: The committee has raised at least $27 million. At least 378 gave the maximum $50,000, including actors Halle Berry and Samuel L. Jackson, Hollywood producer Jeffrey Katzenberg, director Steven Spielberg and entertainer Barbra Streisand.

The inaugural committee said the "Youth Ball" for people aged 18 to 35 would celebrate "the role young Americans can play to serve their communities." Tickets will be available for a reduced price of $75. Most inaugural ball tickets are $150.

The committee also announced regional inaugural balls for guests from the Midwest, West, East, South and Mid-Atlantic regions of the country, as well as balls for guests from Obama's home states of Illinois and Hawaii and Vice President-elect Joe Biden's home states of Delaware and Pennsylvania.

"This is America's inaugural celebration in every way," presidential inaugural committee executive director Emmett S. Beliveau said in a statement. "Young people are more engaged in this country's future than ever before and we want to harness that excitement by inviting them to participate in this historic occasion. In that same vein, we are hosting events to bring people from all walks of life and from across the country."

The committee said there will be a total of 10 inaugural balls:

• Youth Inaugural Ball -- Washington Hilton
