WWE Diva Emma has got to be kicking herself ... she just lost her prized job over a stupid iPad case she wanted so badly ... she stole it.
Emma was busted Monday by Hartford, CT cops after Walmart security claimed she had just left the store without paying $21.14 for the case.
The WWE acted fast, but didn't prejudge her. Emma already copped a plea and was sentenced to 1 day of community service.
Sometimes when you save money, you don't always live better.
