Cirque filed a lawsuit against Timberlake and his producer for their song "Don't Hold the Wall" ... from the "20/20 Experience" album. Cirque thinks the hitmakers sampled a tune called "Steel Dreams."
Yes, Cirque does more than acrobatics ... it actually dropped an album in 1997.
It wants a cut of all profits Justin and Timbaland made off 'The Wall.' Unlike most JT songs, it was no commercial success -- never cracking Billboard's Hot 100.
