Erin Andrews -- Tearful Testimony in Peeping Tom Case

Erin Andrews broke down on the stand Monday as she testified about how she learned she was secretly recorded through a peephole in her Nashville hotel room in 2008 by Michael David Barrett.

Andrews' testimony was part of her $75 million lawsuit against the Nashville Marriott and Barrett ... who got a two-year prison sentence after pleading guilty to interstate stalking.

Her father Steve testified last Wednesday, saying his daughter is "a shell of her former self" because of the video.
