The Black Eyed Peas kicked off the new season of Oprah Winfrey's daytime talk show in stunning fashion on Tuesday (08Sep09) by staging the largest single city 'flashmob' dance event ever.
Without the show host's knowledge, Peas star teamed up with choreographers to create a dance routine for the band's I Gotta Feeling hit and then called on 800 fans to help him carry out the spectacle on TV.
The 800 were taught the moves and then they passed them on to another 20,000 Oprah fans, who showed up for the taping of the TV titan's free block party show in Chicago, Illinois.
The amazing finished product aired on TV in America on Thursday (10Sep09) - when more than 20,000 people took over Chicago's Michigan Avenue and wowed Winfrey and with a colourful synchronised dance routine.
After the performance, the singer/rapper told Oprah, "I didn't think it was going to be this spectacular... You talk about crowd participation, this is beyond... This is incredible."
And the host screamed, "That is so cool. That is the coolest thing ever... Chicago, I love you."
