Will.i.am has done it again. The multiplatinum-selling rapper-singer-producer behind the Barack Obama-boosting viral blockbuster “Yes We Can” posted a new music video promoting the Illinois senator’s presidential run this morning. Check out “We Are the Ones” here.

Since going online in early February, “Yes We Can” (which features various and sundry boldfaced names including Scarlett Johansson, John Legend and Laker great Kareem Abdul-Jabbar singing and reciting an Obama campaign stump speech) has been streamed some 16 million times. “We Are the Ones” similarly showcases an eclectic array of boldfaced names — Jessica Alba (pictured, from the video), Ryan Phillippe, Macy Gray and George Lopez among them — chanting “Oh-bah-ma! Oh-bah-ma!” over a hip-hop beat with sparse piano accompaniment. Some of them also sing or alternately explain their aspirations for candidate and country.

“I think the thing that inspires me the most about Barack Obama is that he really is going to be the president of the United States,” says actress Kerry Washington. “He’s not going to be the president of the top 10% or the president of the most powerful corporations or the president of the most powerful lobbyists. He’s going to be our president.” According to a spokeswoman for the video, will.i.am put the song’s music together in just two hours. And he didn’t so much enlist the celebrity contingent (which also includes “Ugly Betty” star Eric Mabius, John Leguizamo, Regina King, actor Luis Guzman and rapper-singer Tyrese) as they enlisted him. The Black Eyed Peas frontman went forward after scores of famous well-wishers asked him if they could be part of a subsequent pro-Obama viral video. “Everybody came to him,” spokeswoman Elina Heng explained of will.i.am. “There wasn’t too much outreach on his part.”
