In November 2017, Fontaine participated in Queens United/Reinas Unidas, a benefit show organized by Phi Phi O'Hara in support of Puerto Rico following Hurricane Maria. The show raised over $80,000. Fontaine stated, "Puerto Rico, you are part of our heart in the United States of America. I'm Puerto Rican. I love you from the bottom of my heart, and you've got our support." In September 2018, Fontaine became the third drag queen ever hosted at Bowdoin College in Brunswick, Maine. Previous drag queens performed there in 2012 and 2015. The event, hosted by the Latin American Student Organization, included a performance and interview, which "touched on themes of family, health and getting out of one's comfort zone." On her YouTube channel, Fontaine has two shows: "CuCu Confessions" and "Memoirs of My CuCu". She also headlines a one-woman show called "Cynthia Lee Fontaine: More Intimate CuCu Confessions", which she performs around the United States.
