Rapper B.G. -- I'm Ready to Go to Prison

Former "Hot Boys" rapper B.G. says he's mentally prepared to begin his 14 year prison sentence for gun possession and witness tampering ... telling TMZ he's focusing on the light at the end of the tunnel.

As we previously reported, B.G. -- aka Baby Gangsta ... aka Christopher Dorsey -- pleaded guilty to crimes stemming from a messy 2009 traffic stop.

Now, B.G. released a statement through his rep Tracey Smith ... saying, "I am relieved I found out what my fate was yesterday because I was facing 30 years and my case kept getting pushed back."

The 31-year-old adds, "I am just ready to get my sentence started because it’s not RIP BG it’s FREE BG ... I feel happy and blessed that I will still be a young man and still be able to see daylight because I am someone, a dad, a brother and a son."

B.G. says he expects his career to continue to thrive while he's locked up ... noting, " will have upcoming music that will be released while I am away."
