About a week ago, Steven Spielberg's daughter said she's a porn star. Now Radar reports that Mikaela Spielberg has been arrested and charged with domestic violence in Nashville, Tennessee. An inmate report shows the 23-year-old was collared Saturday morning, booked soon after, and put under a routine "12-hour hold" even though her $1,000 bond was posted. Her fiance, Chuck Pankow, confirms the arrest to Fox News but calls it "a misunderstanding. No one is hurt." People recalls that Mikaela was adopted by Spielberg and his wife Kate Capshaw into a family that includes six other children. Anyone experiencing domestic violence is urged to call the National Domestic Violence Hotline at 1-800-799-7233 or go to thehotline.org. (See how Mikaela's porn announcement went down.)
