Actress Shirley MacLaine is 90 years old, so she knows a thing or two about living a long life. And apparently she has a secret to her longevity—one she shared with Billy Eichner (which he recently shared in a new interview with PEOPLE).
The duo worked on a movie together in 2019—the Christmas film Noelle starring Anna Kendrick and Bill Hader—and it was during that time MacLaine let Eichner in on her little secret. While chatting with the magazine in support of the new film Mufasa: The Lion King, Eichner recalled working with that film's stacked ensemble cast, which included "friggin' Shirley MacLaine, who told me the secret to living long."
