Ashley Timms, 22, demanded £15,000 from the star, who cannot be named for legal reasons.
Timms, from Middleton, Greater Manchester, made a series of threats to publish the images if he was not paid the cash.

The sex video clip involved a woman and the footballer engaged in sex at his home.
Timms pleaded guilty last month and was jailed at Manchester Crown Court after admitting making a series of unwarranted demands with menaces.

Rob Kearney, mitigating, said Timms came from a decent family of police officers, solicitors and teachers, but was not academically bright though he was good at sport.
He was seen as a potential Premiership footballer after signing for Manchester City.

"That allowed him to enter into a life most people would dream about, a fantasy world of money, fast cars, jewellery and girls. What is often described as the high life,'' he said.

But his career began to falter. He was released by Manchester City and dropped down the leagues, flitting between clubs including Altrincham, Atherton LR, Curzon Ashton, Mossley, Shrewsbury Town, Runcorn and Accrington Stanley.
He also had trials at Norwich City, Bolton Wanderers, Fulham, Oldham and Macclesfield.

Mr Kearney said: ''The fantasy life he dreamed of was gone. He experienced difficulty accepting that. He was hanging on desperately to his dream.''

Timms showed no emotion as he was led to the cells but his mother and other relatives sobbed at the back of the court.
Passing sentence, Judge Andrew Gilbart said: "Blackmail always calls for a custodial sentence.
"The abuse of your friendship for simple greed is an aggravating feature."

David Friesner, prosecuting, told the court Timms used a mobile phone to video the international footballer having sex with a 19-year-old woman at the player's home last September.
Timms was arrested on April 4. The video footage was never recovered and Timms said he had destroyed it.
