There is said to be some legit heat between SmackDown Divas Michelle McCool and Natalya Neidhart. It's all due to a recent incident involving the two.
McCool reportedly tried to re-teach Natalya, an 8-year wrestling veteran, on how to lock up correctly. She also wanted to show her how to work "WWE style." Apparently, Neidhart didn't take McCool's attempt to teach her on her wrestling too well.
