Full House actor John Stamos can sleep easy – a judge found his extortionists guilty of conspiracy in a Michigan courthouse on Thursday.

FIRST PHOTO: John Stamos and Alleged Extortionist’s Night Together

Scott Sippola, 31, and Allison Coss, 24, were convicted and sentenced to five years behind bars after the FBI launched a sting operation last year and it was discovered the duo was attempting to release incriminating photos unless Stamos paid them.

The extortionists contacted Stamos via email and demanded $680,000 from the actor in exchange for keeping the photos and information private.

An affidavit from an FBI agent said that Stamos, identified as "Mr. X", attended a party with Coss in 2004 during which photos were taken.

Stamos’ attorney claimed the photos never existed and no photos were ever found by FBI agents.

John Stamos released the following statement:

“I would like to thank the court, the FBI and the US Attorney’s office for their swift and efficient dealings in connection with this case.  

"I am shocked and perplexed how individuals could fabricate so many false stories in an effort to defend a crime.  I agreed to be a witness for a federal criminal prosecution and endured countless false accusations about my behavior and appropriateness.  The allegations made regarding an inappropriate relationship are completely untrue.  These slanderous allegations to smear my reputation were part of their defense to redirect attention away from the federal crime of extortion.  There was no hot tub, no drugs, no nudity and nothing sexual in nature involved in my friendship with this woman.  They lied about everything from a pregnancy to compromising photos.  

"I'm grateful these two criminals have been found guilty and I plan to go home to be with my family and friends and prepare to get back to work.”

On Monday, Full House star John Stamos faced his alleged extortionist Allison Cross in a Michigan courtroom as a cozy photo of their first night together surfaced on the internet.

The photo, which was obtained from a social networking page of Coss by Crimesider according to CBS News, shows Coss and Stamos hugging for the camera.  "First time I met this werido [sic]..." the caption read.

Stamos and Coss had a fling in 2004 when she was only 17-years old while she was on spring break in Florida. The actor allegedly invited Coss and a female friend to his hotel room where he was photographed with hanging out with strippers and leaning over a table covered with cocaine. Stamos has said that he was “heartbroken” over his recent separation from his wife when the meeting with Coss occurred. The two continued an e-mail correspondence after the night in question.

However, things eventually went south when Scott Sippola, a 31-year old Michigan nightclub owner, tried to turn Coss and Stamos’ relationship into a moneymaking scheme. Stamos contacted the FBI after a man identified as “Mr. X” reached out to him asking for money to ensure Stamos’ reputation would not be tarnished by scandalous photos. A sting operation was set up and Sippola and Coss were arrested at a Michigan airport.

Coss and Sippola have pled not guilty to charges that they attempted to extort $680,000 from the actor in exchange for not releasing the photos of him .
