Jay-Z has been slapped with a lawsuit by wrestler Diamond Dallas Page for unlawful use of his 'Diamond Cutter' hand signal.

Page, real name Page Falkinburg, filed the lawsuit in Los Angeles Federal Court, claiming he trademarked the rights to the diamond-shaped symbol in 1996 and has used it for wrestling and other entertainment ventures on multiple occasions.

Page contends that Jay-Z, real name SHAWN CARTER, started using the diamond symbol years after on various commercial products.

The wrestler, who uses the sign on the cover of his new book YOGA FOR REGULAR GUYS, also says he used the symbol at monthly fighting events and media appearances, reports AllHipHop.com.
