50 Cent is giving his new album away for free.

The "In Da Club" rapper plans to celebrate his 37th birthday on Friday by offering fans the chance to download his latest musical project 5 (Murder by Numbers) for free.

Fifty - real name Curtis Jackson - shared the news via a series of Tweets, Writing, "I'm listening to album 5 this joint banging. I'm giving it away as a birthday present to my self cool right? You can't buy album 5 it's FREE street king immortal will be for sale. My official Interscope album is called STREET KING IMMORTAL due out in nov (sic)"

The album is his first since 2009's popular Before I Self Destruct and has taken a long time to complete, due to disputes with his label Interscope Records. The hip-hop star's next official Interscope album, Street King Immortal, has finally been scheduled for release in November after being delayed since 2011, which 50 has previously blamed his record company for, accusing them of "moving in slow motion," on the project.
