Well, that's odd.

Just days after it was reported that Nicole Kidman was heartbroken for husband, Keith Urban, after his father's death, the 48-year-old actress was noticeably absent from Robert Urban's funeral.

While Keith, also 48, was surrounded by family and friends for the unfortunate occasion on Thursday, Dec. 17, his wife was sadly nowhere to be found. The country star — who seemed noticeably upset without Nicole by his side — sported a black suit and black tinted sunglasses at the somber event held in Sydney, Australia.

Keith previously revealed his dad, Robert, passed away after a long battle with cancer on Saturday, Dec. 5. "I've been deeply touched by the outpouring of love and support that [Nicole] and I, and our family, have received since my Dad’s passing on Saturday night," the singer said.

Nicole's failure to attend her father-in-law's funeral is especially shocking considering she herself lost her dad only a year ago. “They have truly been there for each other through thick and thin,” a friend of Keith’s previously told Closer of the couple. “They have one of the most harmonious relationships in show business.”
