'Love & Hip Hop NY' star Mendeecees Harris is now going by "Inmate Harris" after checking himself into federal prison in Pennsylvania.
Harris got 8 years for drug trafficking charges. He'll do his time in a minimum security prison where inmates can watch TV and the meal program is top notch ... something different everyday for 8 weeks.
He's already served 15 months for his crime, so he actually has less than 7 years left to serve.
As we showed you, Harris made the most of his last few days of freedom.
