At the beginning of last month, Katherine Heigl visited Esslingen in Germany, the hometown of her maternal grandfather Reinhold F. Engelhard. As part of her visit she enjoyed a guided tour through the historic city, an event covered by national television station RTL, who conducted an interview during her walk around the ancient streets of the town. During the tour, she made an unscheduled stop at a small hat boutique when the window of local designer Birgit Sophie Metzger’s shop caught her eye.
