50 Cent has responded to claims from The Game that he was in fact the writer behind 50’s 2003 hit 'What Up Gangsta’.

The song originally appeared on 50’s 2003 debut album, 'Get Rich or Die Tryin'. The following year, 50 Cent wrote a number of songs for The Game’s project "The Documentary."

In a conversation back in March, The Game’s associate Wack 100 revealed that The Game had claimed to have written "What Up Gangsta."

Asked about 50 Cent’s contributions to 'The Documentary’, Wack said: “I’m going to speak on something you don’t ever speak on,” while reciting the track’s chorus: “'What up cuz, what up Blood, what up Gangsta.”

He added

Who do you think wrote that? I’mma leave it alone... "Bro, just don’t be beating his chest.”

Referring to the claim in a new interview on The Breakfast Club, 50 Cent said: “[The Game] said he wrote 'What Up Gangsta'." I’m like, "C’mon on, bro." You weren’t even around when we did that. That was before you even came into the picture.
