A man was sentenced Tuesday to nearly 11 years in prison after pleading guilty to robbing "Girls Gone Wild" creator Joe Francis and forcing him at gunpoint to pose for a demeaning videotape as part of an extortion attempt.

Darnell Riley, 28, was sentenced after he pleaded guilty to robbery and attempted extortion as part of a deal with prosecutors who agreed to drop burglary, carjacking and kidnapping for ransom charges.

Los Angeles Superior Court Judge Michael Kellogg sentenced him to 10 years and 8 months in state prison.

Francis testified during a preliminary hearing in December that Riley broke into his home Jan. 22, 2004, pulled a gun and bound and gagged him.

He said Riley forced him to partially disrobe and make sexually humiliating comments about himself. Francis also testified that Riley threatened to distribute the video unless Francis paid him $300,000 to $500,000.

Police learned of the alleged crime from socialite Paris Hilton, Francis' former girlfriend. Hilton said she heard the incident discussed on the party circuit.
