Here's the exact description from wwe.com:
------------------------------------------------------------------
Joy, Michelle, Rochelle and Lauren will compete in three sexy events to determine the SmackDown! Rookie Diva of 2005.
There will be Swimsuit, Evening Gown and Talent competitions, and the winner will be decided through arena and on-line voting among WWE fans.
-----------------------------------------------------------------
Riiiiiiiiiiiiiight
Winner (not the fans): Joy (even though I hate her, she's been given most TV time aside from the one with the gross lips)
How???: Crowd response...?
I also keep hearing rumours of a Booker T/Heidenreich match, but with the proposed Tag match now off at Mania, Booker and Heidy could save it till then instead, unless WWE.com states otherwise that's the full card
(If this happens: Winner: Booker; How: Pin after Scissors Kick)
