According to TMZ, rapper Juvenile was arrested for violent fight at a Miami nightclub.  Juvenile reunited with Lil Wayne on stage for a performance but end up in jail before the night was over. 

Rapper Juvenile, real name Terius Gray,was involved in a fight that started inside the club but quickly moved outside.  Club security guards were unable to diffuse the situation so they called for law enforcement officials to intervene.

No official word has been given on Juvenile's involvement in the incident.  He has not been released from jail at this time.  I hope this was a huge misunderstanding and things will clear out.

Juve and Wayne -- who were in the Hot Boys together back in the late '90s -- had a long running beef when the group broke up ... and last night was the first time they have been on stage together since the feud.

But around 7AM, cops say Juvenile -- who's listed at 5'11, 150 lbs -- was involved in a fight that began inside the nightclub and spilled outside to the front of the hotel.

Security told police the people involved in the fight were "creating a threat to life and property as well as the overall safety of the patrons inside."
