50 Cent has blasted his record company for "moving in slow motion," to get his next album out.

The 'In Da Club' rapper - who is signed to Interscope Records - has his fifth album 'Black Magic,' ready for release but has clashed with the label about when and how to release it.

He tweeted: " Ok I tried to be cool with my record company . I went to the meeting talk to everyone and s**t feels like there moving in slow motion.

"I worked really hard on this album I'm not gonna let it come out like some bulls**t. There use to me just putting it out (sic).

"My whole career iv been doing s**t and they have been playing catch up this is the last f**king album THEY BETTER WAKE UP AND WORK."

50 - real name Curtis Jackson - further warned fans if he can't reach a compromise with the label soon, the album, his first since 2009's 'Before I Self Destruct' - could be delayed until next year.

He tweeted: "I'm sorry to announce I will not be releasing a new album this year if we don't get on the same page.

"I would rather not launch my album without a plan the whole system is executing. I don't know why they play with me, they know how I get. (sic)"
