Brad Paisley and Carrie Underwood will be hosting the CMA’s tonight. Show starts at 7 on ABC.   Brad Paisley will also be on Nightline with his wife, "Nashville" actress Kimberly Williams-Paisley.   The two are talking about being the victims of an  elaborate hoax that started with an email from a total stranger.

During the interview Kimberly Williams-Paisley told Nightline that a woman reached out to her over email, posing as a mother who had a dying daughter.  Mom said the child was dying of a neuroblastoma, a type of pediatric cancer.

Kimberly told Nightline, "She said that her daughter, Claire, had begged her to get in touch with me".

The correspondence increased with Kimberly and the mother exchanging dozens of emails, phone calls and texts. The mother even sent pictures of Claire, along with pictures of journal entries and recordings of songs that the girl had supposedly sung for Kimberly.

Brad Paisley, also got on the phone and sang "Amazing Grace."  to the dying child.

But Nightline reports the story started to unravel after "Claire" died and the mother would not provide an address for the Paisleys to send flowers for the funeral.

It turns out that the photos of the sick girl had been taken from the blog of a real girl in Southern California who had neuroblastoma.

And  the Paisleys are not the only celebrities who were scammed. During the course of a year-long investigation, "Nightline" has learned of at least a dozen others who heard similar sob stories, including the band Little Big Town, the reality television star Kate Gosselin, members of the Dallas Cowboy Cheerleaders, and other singers.

"Nightline" tracked down the person responsible at a campground in Wyoming, you can see the confrontation on a special edition of "Nightline" Wednesday, Nov. 6 at 11:35 a.m. Central Time.
