Attention, Desperate Housewives fans:

We hope you're sitting down, and wearing your thinking caps!

According to Entertainment Weekly's Michael Ausiello, the show will conclude its season on May 17 with a shocking wedding.

The identity of those walking down the aisle are so hush-hush that even members of the cast and crew have no idea who is getting hitched.

"People are being told on a need-to-know basis," said a show insider. "Marc [Cherry] doesn't want a repeat of last year when the flash-forward thing leaked."

Let the guessing games begin! Who do you think will be getting married?
