A Playboy playmate was charged with firearm offenses after attempting to board a plane in Florida with a loaded handgun in her bag, the Orlando Sentinel reported Wednesday.

Shanna Marie McLaughlin, Playboy's Miss July 2010, was arrested around 6:35pm Monday at Orlando International Airport as she attempted to board a plane to Los Angeles.

The 26-year-old, who has a valid permit to carry a concealed weapon, told police that the bag she was carrying was hers, but that she did not know that her boyfriend had put his loaded .45 caliber Colt revolver in it.

The model was jailed Monday on charges of carrying a firearm in a place prohibited by law, but has since been released, the Sentinel reported.

McLaughlin's former school, the University of Central Florida, had to apologize publicly last year after she was photographed scantily clad in a sports locker room for a magazine spread.

McLaughlin was back in the headlines last month when she publicly lent her support to Playboy founder Hugh Hefner, who had been criticized by his former fiance Crystal Harris over his sexual prowess.
