Maino has been waiting 21 years to see his boy Casino Mike a free man.

They were reunited this week, and you can see what a joyous occasion it was.

Reunited...Tears of Joy!!! After 21 years my brother free. Unbelievable the feeling. Damn! Y’all just don’t know. #CasinoMike #LilNiggasThatBecameOGs #PartyAndPain

Maino, who did a decade in prison himself, celebrated his Bed-Stuy Brooklyn buddy and explained their relationship in several other IG posts.

#Repost @mainohustlehard (@get_repost) ・・・ Finally my Brother coming home!!!! Once upon a time we were Lil niggas that wanted to be Big niggas. And then we got old enough to play grown. Maybe that was when all the Trouble started, except we didn't realize it was trouble at all. I sit back and think about us, our lives and can't help but feel like those Streets and Prison Yards robbed us of our youth, and true potential in life. I guess had we known what we know now, things would be a lot different...but unfortunately we can't live life Backwards, and all we can do is keep pushing. Continue to strive. But just know that every time I smile, it's a smile for my friends that can't or the ones that are too far away confined to cell walls. One time for my Lost Loved Ones...I'm still tryna give'em the Truth. These Rappers not telling the Whole Story! #TBT 'Me and Casino Mike"
