Beyonce Sued For Lifting Sample On 'Formation'

Beyonce stole a famous recorded line from a dead New Orleans rapper and then sampled it in her song, "Formation," without permission ... according to a new lawsuit.

The estate of Anthony Barré -- aka Messy Mya -- just filed suit against Bey for allegedly using a small, but memorable, piece from his 2010 video "A 27 Piece Huh?" and sprinkling it into her hit song ... which has been certified gold.
