Pam Anderson invades the Big Brother house (in Australia - sorry U.S. guys)

I'm not quite sure why this happened, but buxom actress/model/sex tape entrepreneur Pamela Anderson made a guest appearance in the Big Brother house on the Australian version of the show. TV Tonight has the rundown of the appearance and a bunch of pictures. Someone uploaded video of the show here. I like how the announcer introduces her as an author.

Doesn't Australia have any scantily-clad, silicone-enhanced actresses of their own that could have made an appearance?

Anderson visited the Diary Room, surprised the contestants, and then they had a big dinner with food and booze. Apparently, Anderson is going to spend three days in the house, which means that everyone will be tuning in to those segments where they film the contestants taking a shower.

I think Anderson should start doing this on all reality shows. It would be kinda funny to see her airlifted onto the Survivor island in the middle of the game with no warning or explanation from Jeff Probst at all. She can play along and just say "I have no idea how I got here!" Or have her be the prize in the one of the challenges. She can hide inside a crate of food and matches and just pop out when the winning team opens it.
