Gucci Mane Released from Jail

Rapper Gucci Mane has just been released from jail in Georgia after spending nearly three weeks behind bars, TMZ has learned.

As we reported, Gucci was arrested April 13th for a probation violation. He's been in jail since.

Gucci's attorney, Drew Findling, tells us, the probation violation was triggered by a March 25th incident at an Atlanta nightclub ... when Gucci allegedly bottled a clubgoer in the head, causing a massive gash.

Gucci was charged with aggravated assault in connection with the incident. That case is still pending.
