Shellie Zimmerman made the comments to ABC on Wednesday after pleading guilty to a misdemeanor perjury charge for lying during a bail hearing following her husband's arrest for the fatal shooting of 17-year-old Trayvon Martin in February 2012.
She also said she wasn't home the night of the shooting because she'd had a fight with her husband.
She says the couple lived "like gypsies" in the months after George Zimmerman was released on bail, spending nights in a 20-foot trailer deep in the woods.
Her husband wasn't in court with her as she was sentenced to a year's probation and 100 hours of community service.
He was acquitted of second-degree murder in July.
