All O.J. Simpson wanted was a few extra cookies. 

According to the Daily Mail, Simpson, who was sentenced to 33 years in prison in 2008 for kidnapping and armed robbery, was reportedly caught by guards tying steal more than a dozen oatmeal cookies, which is a violation of prison rules. 

Simpson, who's imprisoned at Nevada's Lovelock Correctional Center in Pershing County, reportedly tried to smuggle the cookies into his cell after lunch. One of the guards noticed the 66-year-old hiding something under his prison clothes. 

"O.J. just stood there with a goofy grin on his face as the guard kept digging inside his shirt and throwing the cookies on the floor," a source told The National Enquirer.

Simpson's fellow inmates were reportedly on hand to witness guards expose his sweet tooth.

"When the guard started pulling cookies out of O.J.'s shirt, the other inmates started laughing so hard they nearly fell over," the insider told the Enquirer.

Simpson was reportedly let off with only a warning, but suffered humiliation at the hands of fellow inmates and was in strict violation of doctor's orders.

"Everyone thought he had smuggled in a cell phone or some other kind of contraband, so when the guard started pulling cookies out of O.J.'s shirt, the other inmates started laughing so hard they nearly fell over," a source said. "O.J. just stood there with a goofy grin on his face as the guard kept digging inside his shirt and throwing the cookies on the floor."

Reports have stated that doctors previously warned O.J., a severe diabetic, to clean up his diet and start exercising more or he could be dead within months. 

The former Buffalo Bills Hall of Fame running back reportedly weighs around 300 pounds and has high blood pressure.

"But the temptation of the cookies in the prison chow line was too much for him," the source said. "O.J. has been trying to diet since the doctors talked to him, but he loves sweets, and after a few weeks he couldn't take it anymore."

The Los Angeles Times has reported that the story of Simpson's theft is no true. A spokesperson for the Lovelock Correctional Center said on Friday in an email there was "no validity" to the story of Simpson stealing cookies.
