Will.I.Am went through a lot of trouble to record a song entitled "Smile Mona Lisa." He obtained access to the Louvre Museum in Paris at two in the morning so he could record the song in front of the very portrait the track gets its namesake from. He told reporters about recording in front of Leonardo da Vinci's work, saying, “I wanted to capture the ambiance of the Louvre that Mona Lisa lives in."
