''Transformers' made her a star and I expect her costumes to perform very well at auction. The 17-foot Bumblebee robot speaks for itself ... it's such an amazing spectacle and a pop culture icon that I expect bidders to go crazy,' said Maddalena.

The disassembled robot is currently stored in boxes. All the items were consigned by the films' Viacom Inc-owned distributor, Paramount Pictures, and director, Michael Bay.

Bids can be placed in person at the auction in Calabasas, outside Los Angeles, by phone or live on the Internet.
