Singer Katy Perry and Disney CEO Bob Iger attended the star unveiling and dedication.
Mickey was the first fictional character to be added to the Walk of Fame.
The star will be presented to Minnie during a ceremony Monday morning. "This really is the best day ever". "Thank you, thank you, thank you", she squeaked from the red and white polka dot stage.
"In true Hollywood fashion, she delivered a truly memorable performance but Mickey got all the credit", Iger said during Monday's ceremony.
Katy Perry and Minnie Mouse are a match made in heaven. "To this day, no one rocks a bow, the color red or a polka dot quite like her!"
