The 30-year-old Gallagher, who finished second to New York firefighter Tom Westman on "Survivor: Palau" earlier this year, was stopped in her hometown of Merced, Calif., about 2 a.m. Thursday (Sept. 1). She was charged with DUI.

The advertising exec was detained for the rest of the night at the Merced County Sheriff's Department before being released Thursday morning. A sheriff's spokesman tells the Fresno Bee that his department is required to hold DUI suspects until they sober up.
