ET was at the opening of Madame Tussauds Hollywood when Mayor Antonio Villaraigosa unveiled Los Angeles' new attraction at a ribbon-cutting ceremony.

Watch the video and check out the contemporarily designed, multi-story wax museum. It's the first time that the world-renowned, 200-year-old institution, which debuted in London, has opened a Hollywood edition.

This September, ET's Mary Hart's wax figure will be unveiled at the $55 million museum, located at the corner of Hollywood Blvd. and Orange Drive.
