Taylor Swift shakes off lawsuit

Representatives for Taylor Swift on Tuesday rejected a copyright infringement lawsuit filed by two songwriters over Swift's hit song Shake It Off as a "ridiculous claim".

Songwriters Sean Hall and Nathan Butler said in a lawsuit filed in the United States federal court in Los Angeles that Swift's song used the phrase "players, they gonna play, and haters, they gonna hate" that they had coined for a 2001 song Playas Gon'Play by R&B girl group 3LW.

"This is a ridiculous claim and nothing more than a money grab," Swift's representatives said in a statement. "The law is simple and clear. They do not have a case."
