WWE Diva AJ Lee Collapses It's an H2O No-No

WWE Divas champion AJ Lee collapsed during a match in the U.K. today ... and we're told she was just really really thirsty.

The 26-year old wrestler fainted in the ring Friday while wrestling Brie Bella in London, and dehydration was to blame.

According to reports AJ -- real name April Mendez -- was tended to at ringside after the scary fall ... and walked to the back on her own power.

We're told WWE medical staff continues to monitor her ... just to be on the safe side -- and also because she's really hot.
