Chipmunk is suffering from "exhaustion".

The 18-year-old rapper - real name Jahmaal Fyffe - has cancelled all forthcoming appearances after posting a series of disturbing messages on his Twitter page, hinting he wanted to commit suicide.

A statement from his record company read: "Since finishing his A-levels and completing work on his album, Chipmunk has been working incredibly hard on generating a successful music career which has taken its toll on such a young artist.

"Label and management have agreed to cancel all upcoming promotion and personal appearances to give him some much needed time off."

The 'Chip Diddy Chip' rapper had sparked huge concern for his welfare after posting on his page on the social networking site.

The messages which have since been removed from the site, said: "I Want to Die" and later he asked: "Is suicide easy?"

The rising star - who beat Kanye West and Eminem to be named Best Hip-Hop act at the Music Of Black Origin Awards (MOBO) in September - has since reassured fans he was overcoming his problems.

In an update on his Twitter page, he wrote: "This has been the most difficult time for me... But I will get through it!"

It is now thought that the rapper is resting with his family at home in north London.
