Rey Mysterio Joining Alberto Del Rio For AAA's Triplemania?

The AAA promotion in Mexico has reportedly contacted Rey Mysterio to appear at this Sunday's Triplemania event and they are said to be under the impression that Mysterio will likely agree and appear on camera as a special guest.

This is the same event that Alberto Del Rio is being advertised for.

No word yet on how WWE might react to this considering that Mysterio is still technically under contract with WWE, even though it's rumored that he's been trying to get out of his contract for a while now.
