She's living with family and works for them on the weekends (the wedding business referenced in the video). One of her sisters is away at college, and the others don't live with her. I can't find anything saying why she needs multiple jobs.
She's helping to pay for her sister's tuition at Texas A&M and helping the family take care of her other sibling by paying them.
Anyway, she's had her "conviction" vacated by the judge. Of course, the judge would never have done so without all the negative media attention he's received.
