50 Cent has hit out at Kanye West in a new track.

'Heartless Monster' will be included on Fiddy's 'Before I Self-Destruct' album and slams West for singing on his latest LP 808s & Heartbreak, instead of rapping.

Some of the lyrics to the song are: "It's the return of the heartless monster / I should give you n***ers a whole R+B record / 808s and my heart's broken / I hate all these f***ers with the rainbow colours on."

50 Cent criticized Kanye at the time '808s & Heartbreak' was released.

What a loser, dragging this out. I hope he flops hard.

He's so desperate. I love it.

50 is over

Well we all knew this one was coming.

50 is just irrelevant now. He should collaborate with Christina.

And lets see if 50 can reach half the sales of "808s"

Maybe 50 Cent should sing as well, it made Kanye's music so much better.

50 Cent is so done, irrelevant and desperate for attention. I haven't heard any music from him since I Get Money. It seems he can only get attention when he goes off on these jealous rants about Kanye.

This whole thing screams "desperate".

I like 50 cent but this is pathetic.

LMAO. Trying to use Kanye to sell records again. Pathetic

Looks like someone's still trying to get a release for that 4th album, no?

What an asshole. He probably won't even go Gold.

You can't beat Kanye even with his new style.

I honestly cannot wait to see him flop if/when his album is released.

Dead at the 50 cheerleader.

You're over 50...

WTF? He's desperate

kanye > 50

Kanye's music **** all over 50's career

Seriously, 50 needs to keep quiet. Trash talking is NOT helping his cause.

50, shut the **** up.
