Katherine Heigl is apologizing after a grave mistake where she was taking selfies at a cemetery. The 39-year-old actress posed solemnly at the headstone of her brother, Jason, who lost his life in a car accident when he was 16. Her grandparents are also buried there. She is now acknowledging she blundered when she posed in front of the gravesites of complete strangers. The posts, which she put up on Instagram Sunday, have since been taken down.
