Beyonce's lawyers just got into formation.

The music superstar reportedly filed a response to the lawsuit from late rapper Anthony Barre's estate, which is suing the singer for using a clip of Barre's voice in her single "Formation."

According to TMZ, Beyonce's legal team argued that the use of the New Orleans rapper's voice, who appears on the Lemonade track for about six seconds, is "reasonable and justified."

Meanwhile, Barre's estate claims that the use of his vocal was never signed off on, and that they are owed roughly $20 million in royalties.
