LMFAO was an American electronic dance music duo which consisted of uncle and nephew Redfoo and SkyBlu. Their name was an initialism of "laughing my fucking ass off". LMFAO's members are descendants of Motown Records founder Berry Gordy, Jr.. RedFoo and SkyBlu 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, it was featured on David Guetta's smash hit "Gettin' Over You", which charted all over Europe and the U.S., including reaching number one in the UK Singles Chart.
LMFAO was best remembered for its song "Party Rock Anthem", which reached #1 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; it is also LMFAO's biggest throughout their career. Following the song's release, LMFAO officially announced that they had gone on hiatus.
