Why was Mickie James fired from the WWE?

Kelly Kelly was fired because in the match against Laycool and Dolph Ziggler she teamed up with Edge but Kelly Kelly used the illegal move spear to help Edge (made illegal by Vickie Guerrero a couple days earlier).

But she was also fired because before the match Vickie called out the Diva and told her off for attacking her at the 2011 Royal Rumble during the World HeavyWeight Championship match and for costing Dolph the title because she distracted him by attacking Vickie (his girlfriend). But Vickie made the wrong decision and Kelly Kelly was right about what she said about Vickie the FAT PIG
