Crooner/producer Ryan Leslie, who offered a $1 million reward for the return of his stolen laptop, is now being sued by the man who found it — and never saw a red cent.

Leslie had his MacBook stolen when he was touring around Germany in mid-2010, so he posted a music video on YouTube.com to advertise the generous reward for anyone who retrieved it. After initially offering $2,000, he upped the reward to $1 million because of the amount of “intellectual property” (Cough: Nude Pics: Cough) stored on the computer.

Armin Augstein, a 52-year-old German man, said he came across the laptop in a park one month after Leslie reported it missing. Augstein handed it into police and has been trying to claim his reward ever since. He’s now suing Leslie for $1 million — plus interest.

Augstein filed suit in Manhattan Federal Court this weekend, accusing Leslie of ignoring his emails about the laptop.

“It’s unfortunate my client has to go to such lengths to recover the reward,” said Michael Fischman, Augstein’s American lawyer.

Either Ryan Leslie was harboring some blockbuster beats on his missing Macbook or we’ve got a potential naked photo and/or sex tape scandal on our hands. The singer/songwriter/producer has upped a $20,000 reward to $1 million nearly a month after his laptop was stolen from a car parked outside a nightclub in Europe.

What are you hiding Ry-Ry — because we know damn well it isn’t “intellectual property?”

The singer/songwriter was partying at Loom Nightclub in Cologne Germany last Saturday night when a creep thief stole his laptop and hard drives from the luxury Mercedes he had rented. Leslie says he had a number of “amazing audio and visual projects” stored on the computer and he’s ready to make out a $20,000 check to anyone providing information leading to its safe return.

Anyone wanna start taking bets on when all the new music contained on that computer will leak?
