LMFAO was 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 in 2006 and later became involved in the electro house scene. The duo's 2008 debut single, "I'm in Miami Bitch", moderately entered both the Billboard Hot 100 and Canadian Hot 100. Its 2009 follow-ups, "La La La" and "Shots", both entered the former chart and earned the duo further mainstream recognition. They guest performed alongside Fergie on David Guetta and Chris Willis's 2010 single "Gettin' Over You", which peaked atop the UK Singles Chart and entered the top 40 of the Billboard Hot 100. LMFAO became best known for their 2011 single "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.
