WWE legend Kurt Angle has added an 8th member to his family -- adopting a 15-year-old boy from Bulgaria ... and the story behind it is AMAZING!!!
The kid's name is Joseph -- and Kurt says his wife was adamant about bringing an older child into the family after learning a pretty heartbreaking fact about adoption.
"My wife decided she wanted to adopt a child, but she did some research and found out that kids over 10 don't get adopted, period. So, she decided not to get a young one, but an older one to try to give him a chance.
