Former Hot Boys and Cash Money rapper Juvenile was allegedly arrested over the weekend in Miami.

According to a report, Juve’s arrest was the result of a nightclub altercation.

Juvenile — real name Terius Gray — had just reunited with Lil Wayne on stage at LIV nightclub earlier in the evening … when something went wrong.

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 it was the first time they had been on stage together since the feud.

But around 7 a.m., 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.
