It was scheduled to be released in the UK on May 25, 2009, however due to three alternative versions of the song entering the UK iTunes Top 50 songs, The Black Eyed Peas version was released two weeks early, on Sunday, May 10. One of their full performances took place at the American Idol Finale of 2009, during which the Top 13 girls sang "Glamorous", and then Fergie came out and sang a small part of "Big Girls Don't Cry", eventually switching to "Boom Boom Pow". As of June 2009, an unknown number of North American radio stations have elected to censor the song's reference to satellite radio.[7] Most UK radio stations have also been found to distort the word satellite radio, and this is the version that appears on the UK CD single.
