STAGE TUBE: Idina Menzel Helps Ellen Celebrate Cat Week with CATS Tribute!

On the last day of Ellen's Annual Cat Week, she took a look back at some of this year's most memorable moments with cats. Meow! Below, watch as Idina Menzel helps her reminisce to the tune of, what else, but "Memory."

Menzel's newly released self-titled album is currently in the top 10 on the iTunes charts. The star's voice can be heard as Elsa in Disney's global box office smash "Frozen," in which she sings the film's Oscar-winning song "Let It Go," and in the follow-up short, "Frozen Fever."

Menzel earned her first Tony nomination as Maureen in the Pulitzer Prize winner RENT and won the award for her performance as Elphaba in WICKED. Other notable projects include "Glee" and Disney's "Enchanted." She most recently appeared on Broadway in IF/THEN.
