Taylor Swift's mom Andrea Swift got emotional at her daughter's groping trial. The 59-year-old testified at Taylor's trial against DJ David Mueller, who allegedly sexually assaulted the star. "I was very upset ... I felt like I wanted to vomit. He sexually assaulted my daughter, right there, that guy," Andrea Swift Meuller, who lost his job at radio station KYGO-FM over the accusations, still claims his innocence.
