Bone Thugs-N-Harmony star Bizzy Bone has spoken out to silence false rumours suggesting his dramatic weight loss was linked a drug problem, insisting the gossip is untrue.

The rapper is sporting a newly svelte figure after shedding around 80 pounds (36 kilograms), but he is adamant his massive weight loss is down to cutting out alcohol and taking up a healthy new diet and fitness regime.

He tells, "I'm perfectly healthy... I'm probably the healthiest I've ever been in my life... A brother done (I have) lost 70, 80 pounds. I had to. I was too damn fat, and it was all from alcohol. As far as me drinking and things of that nature, I've gone out maybe six times in a year and six months... Never have I done anything else. No Mollies (ecstasy), none of that s**t. No crack. No coke. The farthest I've ever been is opium back in my younger days... All that bulls**t. I ain't got time for that."

The star goes on to insist he felt obliged to speak out to silence the untrue rumours, adding, "I can't walk into any business places that's (sic) conducting distribution, marketing, promotions and them take me serious if I don't answer these things. So if I leave it out there and say I don't care what anybody say about me it starts affecting my business. I have to say, 'Nah, it nothing like that (sic). I ain't never (sic) done no s**t like that'."
