Britney Spears wrangled boyfriend Jason Trawick, sister Jamie Lynn and dad Jamie for a 45-minute lunch at Nashville’s South Street restaurant recently. The singer, seated next to her beau and looking casual in a flowery sundress, ordered a chef salad, eating a portion and wrapping the rest to go. “She was normal, just like any other person,” a witness tells PEOPLE.
