Cee Lo Green reunited with his boys from Goodie Mob this week ... inside an Indianapolis strip club ... and TMZ has learned the crew treated the stripper ladies to a five-figure thunderstorm.
Cee Lo and his boys met up in Indy for some pre-Super Bowl partying Wednesday night ... and decided to take the festivities over to a local gentlemen's establishment around 1:00 AM Thursday morning.
Sources inside the club tell us ... Cee Lo requested lap dances from "the baddest b*tches in the club" ... and the group rewarded their good behavior by making it rain with roughly $10,000 in cash.
We're told there were other famous people in the club at the time -- including some NFL players -- but they were no competition for Team Cee Lo, who easily commanded the girls' attention.
Guess the change in his pocket was enough.
