Hip-Hop has-been MC Hammer is coming down hard on Jay-Z with a music video that disses the Brooklyn mega-star.
The video for "Better Run Run," released Monday, accuses Jay-Z of being an impostor and stealing Hammer's "swagger."
The video by the "U Can't Touch This" rapper also shows a man impersonating Jay-Z -- in a white T-shirt and a Yankees cap -- running from a Devil-like figure.
"I can see it in his eyes, the boy sold his soul. Devil said, 'I'mma give you the world.' I'd take it, plus give me a girl," the rapper says in a sly reference to Jay-Z's wife, Beyoncé Knowles.
What's behind the beef between the '80s icon and the superstar? Apparently, some remarks by Jay-Z in a new Kanye West song, "So Appalled."
"And Hammer went broke so you know I'm more focused/I lost 30 mil so I spent another 30/'Cause unlike Hammer 30 million can't hurt me," Jay-Z rapped about Hammer's money woes.
