Monday's "America's Got Talent" episode featured a singing contestant with an amazing story to share.
Timothy Poe says he developed a stutter after surviving an RPG blast while serving in the U.S. military in Afghanistan three years ago.
Now, his ex-wife and military personnel contend Poe made it all up.
Poe tells TMZ, the fact that there is no record of the incident is a common problem -- one that Poe says is endemic when it comes to reporting soldiers' injuries in Afghanistan.
We asked Tim to prove it really happened. He said he received treatment at a military medical facility in Afghanistan before being transferred to a medical center in Landstuhl, Germany. Tim says he was then transferred to Brooke Army Medical Center in San Antonio. He did not produce any documents to support his claim....
We asked Tim for ANY hard proof to back his claims -- he gave us nothing, saying he can't release pics or documents for legal reasons.
New "AGT" judge Howard Stern responded to a fan on Twitter
seeking his thoughts on the subject. "If true," the radio shock judge Tweeted, "I'm disgusted."
