Women's March over the weekend and reveals that her mom and sister support her plays by lurking in bathrooms to eavesdrop on theatergoers. Later, the Tony winner chats about her upcoming tour. Watch clips from the appearance below!

Idina Menzel recently starred in the reboot of the classic 1988 film BEACHES. Her 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. After Idina's performance of the multi-platinum song at the 86th annual Academy Awards, she made history as the first person with both a Billboard Top 10 hit and a Tony Award for acting.

Idina 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 roles include Rachel Berry's mother, Shelby Corcoran, on the hit television show GLEE as well as starring opposite Susan Sarandon and Amy Adams in Disney's Enchanted. Idina starred in her own PBS special, Barefoot at the Symphony, with an accompanying live album of the same name, and her highly successful 2015 international concert tour included a sold-out performance at Radio City Music Hall. Idina's most recent Broadway role as 'Elizabeth' in the original production IF/THEN earned her critical acclaim and her third Tony nomination.
