LMFAO (an initialism for Laughing My Freaking Ass Off)[4] was an American electronic dance music duo consisting of Redfoo[5] and Sky Blu.

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.

[9] 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.

[10] 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.

[10] 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.

[12] In 2010, LMFAO was featured in David Guetta's song "Gettin' Over You", which was an international hit, peaking in the top ten in eleven countries and at number one in three of them, including in the United Kingdom.

During the commercial break they also appeared in a Budweiser ad featuring their remix of Madonna's single "Give Me All Your Luvin'", which is included in the video game FIFA Street and on the deluxe edition of her album MDNA.
