There appears to be some beef between MC Hammer and Jay-Z. On a new track released by  Kanye West. Jay raps a verse insulting Hammer, and Hammer fired back on his twitter! Uh-oh, Uh-oh…Uh-oh Uh-oh.

Kanye West has a new track titled “So Appalled” featuring Swizz Beats, RZA and Jay-Z.

It’s what Jay-Z says about Hammer that sets him off. Here’s what Jay said:

“”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,”

In response to hearing this verse, MC Hammer hit up his twitter with these:

“The Answer to Jay comes on Oct 31 ( Devils Nite) ..I saw him coming.”

“@ kanyewest jay-hoe aka #HellBoy Tell Jay Oct 31 (Devils Nite). We’ll see if this record and video ‘Hurt’s Him.’

“You wanted my attention #HellBoy (Jigga) ..you got it,” He also attached a video of him hitting a punching bag for 36 seconds.

He also responded to some of his followers who were on Jay-Z’s side:

“These lil demons and Imps stopping by timeline today … Yes, I dissed yo #Daddy … The dude who made the #Lucifer song … smh,”

“Laughing at these grown men coming on my timeline with they #pompoms waving for #HellBoy (Jigga).”

Better watch out HOV, cause here come the Hammer! MC Hammer has reportedly taken his anger into the studio. Let the Beef BEGIN!

Who wins? Jay-Z or MC Hammer? Which side are you on?
