LMFAO (an initialism for Laughing My Freaking Ass Off or Laughing My Fucking Ass Off) are an American electronic dance music duo consisting of Redfoo and Sky Blu. Redfoo is the youngest son of Motown Records founder Berry Gordy and Nancy Leiviska. Sky Blu is Gordy's grandson and the son of Redfoo's half-brother, Berry Gordy IV, Gordy's son with his first wife Thelma Coleman. Redfoo and Sky Blu grew up in Pacific Palisades, Los Angeles, where they formed the group LMFAO in 2006 and later became part of the electro house scene. LMFAO started building a local buzz through its shows and radio play. In 2010, they were featured on David Guettas song "Gettin' Over You", which charted all over Europe and the United States, including reaching number one on the UK Singles Chart. LMFAO is known for their song "Party Rock Anthem", which topped the charts in the United Kingdom, Australia, Belgium, Brazil, Canada, Denmark, France, Germany, Ireland, New Zealand, Switzerland, and the United States. "Party Rock Anthem" also reached the top five in Italy and Norway and was the third best-selling digital single of 2011 with sales of 9.7 million copies worldwide. In September 2012, the duo announced they would be taking an indefinite hiatus. History 2006–2010: Early years and Party Rock LMFAO began their career in 2006 as part of the electro house club scene in Los Angeles, which at the time featured DJ/producers like Steve Aoki and Adam Goldstein. The duo started building a local buzz through its shows and radio play. Once it had recorded some demos, Redfoo's best friend will.i.am introduced them to Interscope head Jimmy Iovine who gave the green light for them to be signed to Interscope/will.i.am Music. Interscope A&R and will.i.am manager Neil Jacobson told HitQuarters that the demos sounded like "finished records" and that so little artist development work was needed it was essentially a "turnkey operation" for the label. According to LMFAO they were originally going to call themselves Sexy Dudes, but changed their name to LMFAO after telling SkyBlu's grandmother. LMFAO released Party Rock EP on the iTunes music store on July 1, 2008, and released its full album on July 7, 2009. The album charted at number 33 on the Billboard 200 and number two on the U.S. Dance Chart. Los Angeles Times described Party Rock as "14 virtually interchangeable odes to night life."
