Electro pop duo LMFAO, also known as Redfoo and SkyBlu, joined "Extra's" Mario Lopez at The Grove, and explained how they came up with their name.
SkyBlu said he sent an instant message to his grandmother, telling her the group name was going to be called Sexy Dudes. His grandma messaged, "LMFAO, you can't be serious," and the rest is history.
Redfoo, whose real name is Stefan Kendal Gordy, is the son of record producer and Motown Founder Berry Gordy. SkyBlu -- also known as Skylar Gordy, is Berry's grandson (Redfoo is his uncle).
The duo, whose hit album "Party Rock" was nominated for a Grammy, danced a few steps with Mario and even got chummy with their fans.
