'Bling Ring' Leader Nick Prugo -- Quit Complaining, Paris ... I Gave Back $1 Million

"Bling Ring" bandito Nick Prugo thinks Paris Hilton needs to chill about the whole "I robbed you" thing ... telling TMZ he already gave back $1 MILLION worth of stuff and has nothing left to give.

Paris recently did an interview regarding the release of "Bling Ring" -- Sofia Coppola's film based on Nick and his friends robbing a slew of celebs back in '09 -- and when asked about any hard feelings Paris explained, "I don't know what I'd do if I saw them. I'm not a confrontational person. But I would literally be like, 'You guys need serious help. And I want my stuff back.'"

On Friday when our photog ran into Nick -- who was just released from prison in April for the crimes -- he told us there's nothing left in the tank. He claims he gave back $1 million to the victims, including Paris, plus the heiress got most her stuff back.
