Chief Keef hit up Twitter to announce that he is newest member of Gucci Mane's 1017 Brick Squad.

Last month, Gucci Mane kicked popular rapper Waka Flocka Flame off the label.

Chief Keef offers up a younger demographic for the washed-up rapper Gucci Mane.

I think this is a horrible decision for Chief Keef. Gucci Mane is a 34-year-old man who is in out of jail for stupid reasons, and Chief Keef is a 17 year old who just got out of jail. This sounds like a old fool teaching a young fool how to grow into a old fool. I hope this works out for Chief Keef -- he still has a chance.
