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 Guetta’s 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. A year after the hiatus, Sky Blu released his debut solo album titled Rebel Music.
