Today we've got more information about the track, which scorches down on iTunes today. The song is part of a forthcoming EP called From Gainsbourg to Lulu, with the Lulu in question (whose full name is Lucien) singing his dad's hit songs with guests like Rufus Wainwright and Iggy Pop. Johnny Depp and his ex-wife Vanessa Paradis reportedly also have a duet on the album.
Gainsbourg, 26, attended the prestigious Berklee School of Music in Boston, and has previously worked with Beck. (His big sister is Charlotte.)
This isn't the first time Gainsbourg's been mixed with the hippest kids around: In 2006, the album Monsieur Gainsbourg Revisited had Franz Ferdinand, The Kills, Karen Elson, and Carla Bruni covering the French icon's greatest hits.
