Yung Gravy has been Rick Rolled by his own song!

Rick Astley the original singer and owner of the rights to his 1987 super mega hit “Never Gonna Give You Up” has lawyered up and is suing Matthew Raymond Hauri aka Yung Gravy. On Thursday, Astley filed a lawsuit in Los Angeles against the rapper alleging that he gave the 26-year-old permission to use the instrumental from his song but did not allow his voice to be used, neither did he allow him to use an impersonator to mimic him.

"A license to use the original underlying musical composition does not authorize the stealing of the artist's voice in the original recording," Astley's lawyers wrote in the lawsuit, according to Billboard. "So, instead, they resorted to theft of Mr. Astley's voice without a license and without agreement."

"In an effort to capitalize off of the immense popularity and goodwill of Mr. Astley, defendants... conspired to include a deliberate and nearly indistinguishable imitation of Mr. Astley's voice throughout the song," the lawyers continued. "The public could not tell the difference. The imitation of Mr. Astley's voice was so successful the public believed it was actually Mr. Astley singing."
